OBSA — Week 1 (Bigs): Fun in the Sun
Our Big Summer Adventure · Week 1 · Bigs (3.5–5)

Week 1 — Fun in the Sun

The first week of camp. Five days to settle in, build the routines that carry all summer, and end with a sandcastle the whole class made together. June 1–5 · Bigs classroom, ages 3.5–5.

Read this first

This guide pairs with the General Planning Guide — that's where the planning principles, the energy arc, and the full executive-function primer live. This Week 1 guide applies them to Fun in the Sun, built around the Bigs (3.5–5) daily schedule. Week 1 is the highest-stakes week to get right: it's the first week of camp ever for new families, and it's when every routine you'll use for ten weeks gets born. Plan it light. The sand is the vehicle; the real curriculum is the room, the routines, and the relationships.

Section 2 · The Week

The Week Builds Toward Friday

Five days that build on each other — explore the material, learn its tricks, build together, build big, then showcase it. A gentle arc, which is right for the first week.

Section 3 · The Skeleton

The Daily Rhythm

Every day runs the identical clock — and this week each day plan below carries it in full, block by block. Four blocks are fixed by the clock — the two snacks, lunch, and quiet time. Everything else is flex: that's the curriculum.

A note on this theme and the heat. Fun in the Sun lives outdoors, but the Bigs day has two outdoor windows that are very different animals. Outdoor Play, 9:00–9:30, is the cool morning window — the sand anchor goes there, every day. Outdoor Activity, 12:25–1:00, lands in peak Bakersfield heat — keep it shaded and light, shorten it freely, or move it indoors on a hot day (see the heat plan in Section 7). The morning sand block is only 30 minutes, so the indoor Craft and Centers blocks carry the theme the rest of the day. Pre-stage the sandbox before Opening Circle so all 30 outdoor minutes are real building time.
Section 4 · The Plans

Five Days, Fully Planned

Each day is the full run-sheet — every block of the Bigs schedule, in order, so you can print a day and run it from the page. Transition and fixed blocks are kept brief; the flex blocks carry the detail.

Day1
Monday
Welcome to Summer
The first day of camp, ever. Settle in · lightest-content day of the summer — and that's correct.
6:30–8:30

Combined arrival care. All classrooms together — quiet free play, books, a soft welcome until the Bigs room opens.

8:30–8:50
Opening Circle — The Very First Circle

Short and warm — twenty minutes is plenty, and you can end early if attention fades. Three goals, nothing more: every child hears their name, the visual schedule gets introduced, and the attention signal is taught.

Name game — pass a shell or beanbag; each child says their name, the group echoes it back. Visual schedule — point to every card: "This is our day." Attention signal — teach it, name it, practice it three times, make it a game.

This whole week is about sand and sunshine — and on Friday, we're going to build something amazing together.
8:50–9:00

Handwash / bathroom. In from circle. First morning — walk the handwash routine slowly, step by step; you'll run it many times today.

9:00–9:30
Outdoor Play · Free Sand Exploration (anchor)

Sunscreen and hats go on at the door — make it a cheerful routine from day one. Then: no project, no product. Just sand — dig, pour, scoop, discover. Thirty minutes is short, so don't over-structure it; your real job is to learn names, narrate warmly, and be available. This block is reconnaissance — learn who's shy, who's bold, who needs you close.

Materials — sandbox, buckets, shovels, scoops, sun hats, sunscreen. Nothing fancy; the sand is enough on Day 1.

✦ Flexibility today — just a seed. As kids explore, you'll see wet sand and dry sand behave differently. Don't teach it — just wonder aloud: "Huh — that wet sand stuck together, the dry sand wouldn't." You're planting this week's lens, gently.
9:30–9:50
Fixed
Morning Snack

In from the sandbox, wash up. Snack is calm and social — a regulation moment, not a race. Chat about the sand: "What did you dig out there?"

9:50–10:00

Handwash / bathroom. Wash up after snack, settle toward the craft table.

10:00–10:30
Craft — My Summer Sun

Keep Day 1 light. Each child decorates a paper sun and adds their name — these become a "Fun in the Sun" wall display and double as a first keepsake. The point isn't the sun; it's establishing what Craft looks like: come to the table, share the materials, make something, help clean up.

10:30–10:50
Music & Movement

Teach two songs you'll use all summer: the cleanup song and one summer movement song. Sing them, model them, make them fun — the repetition is the point, and starting today means they're second nature by Friday.

10:50–11:20
Centers / Free Choice

Start with a quick room tour: where the blocks live, the book corner, the cozy corner, the bathroom, the cubbies. "This is OUR room now." Then open free-choice centers, including a kinetic-sand table to keep the theme alive indoors. You observe, narrate, connect.

11:20–11:35

Handwash / bathroom. Tidy the centers, bathroom and wash up before lunch.

11:35–12:10
Fixed
Lunch

Calm, social, unhurried. Teachers sit with the children. On Day 1, narrate the lunch routine lightly — where cups go, how we clear our spot — you're building it for the summer.

12:10–12:25

Handwash / bathroom. After lunch, before heading outside.

12:25–1:00
Outdoor Activity / Play

A second, short outdoor block — but this is the hottest stretch of the day. Day 1, keep it gentle: shaded water-table play or shade games. Watch the children and cut it short if anyone's wilting; on a hot day, this is the block that moves indoors.

1:00–3:00
Fixed
Quiet Time

Teach the quiet-down ritual today: dim lights, soft music, the same two or three songs you'll use all summer. The first rest is the hardest one of the year. Today's goal is "bodies rest, room is calm," not "everyone sleeps" — sleep comes as trust builds over the week. Keep a consistent adult near the children who struggle most.

3:00–3:30

Wake-up · handwash / bathroom. Lights up slowly, cots away, bathroom and handwash. A full thirty minutes — no rush.

3:30–3:50
Fixed
Afternoon Snack

Gentle and low-key — the day is winding down. A calm table, easy conversation.

3:50–4:20
Manipulative

Introduce the fine-motor materials for the summer — puzzles, beads, sorting trays. Lean beach-themed where you can: shell sorting, sea-creature counters. Quiet, focused, hands-busy work to close the day.

4:20–4:35

Cleanup & room reset. The children help — cleanup song. Reset the room for tomorrow.

4:35–4:50

Handwash / bathroom. Wash up before the closing circle.

4:50–5:00
Closing Circle

End-of-day recall: "What was your favorite thing about the sand today?" That gives each child something specific to tell their grown-up — exactly what makes a parent feel good at the first pickup.

5:00–6:00
Combined Active Engagement — Departure

The classrooms combine for departure. The first pickup is a conversion moment — give every parent a warm, specific handoff. Not "she had a good day" but "Ask Olivia about the giant hole she dug — she worked on it for almost an hour." A specific handoff tells the parent you actually saw their child.

Day2
Tuesday
Sand Tricks
Can we make sand DO things? · The day flexibility takes center stage.
6:30–8:30

Combined arrival care. All classrooms together — quiet free play and a soft welcome until the Bigs room opens.

8:30–8:50
Opening Circle — A Question to Chew On

Smoother than Monday — they've done this once. Let kids help "read" the visual schedule. Practice the attention signal. Bring a cup of wet sand and a cup of dry sand to circle.

Yesterday we explored the sand. Today I have a question: can we make sand stand up TALL? Can we make it hold a shape? Let's find out.
8:50–9:00

Handwash / bathroom. In from circle, before outdoor play.

9:00–9:30
Outdoor Play · Sand Investigation (anchor)

Open exploration anchored by a question: what does dry sand do? What does wet sand do? What pours, what packs, what holds a shape? Don't lecture the answers — ask, wonder aloud, let kids discover.

Choice — "Do you want to test the wet sand or the dry sand first?" Materials — sandbox, a water source, cups, buckets, simple molds, sun protection on first.

✦ Flexibility today — out loud. When a shape won't hold, resist fixing it. Ask "what's another way?" and wait. The waiting is the teaching.
9:30–9:50
Fixed
Morning Snack

Wash up coming in. At snack, chat about discoveries: "What did the wet sand do that the dry sand couldn't?"

9:50–10:00

Handwash / bathroom. Wash up after snack, settle toward the craft table.

10:00–10:30
Craft — Sand Art

Children drizzle glue on paper, sprinkle sand over it, then shake off the extra to reveal their design. Sensory, theme-true, and forgiving — a glue blob that didn't go to plan is fine, there's no wrong way.

10:30–10:50
Music & Movement

Summer songs plus a movement game: "move like you're walking through deep, heavy sand." Slow, exaggerated, and a little silly.

10:50–11:20
Centers / Free Choice — the Sand Lab

Set up a "Sand Lab" with kinetic sand: kids practice making sand hold a shape — packing molds, building small mounds. The point isn't a perfect product; it's the problem-solving when a shape collapses.

Executive Function · Cognitive Flexibility

A sand shape will collapse. It always does — and that collapse is the most valuable teaching moment of the week. When it happens, do not fix it. Ask: "Oh — it fell. What could we try?" Maybe pack tighter, maybe add water, maybe a different mold.

The moment a child tries a second approach after the first one failed, that is cognitive flexibility being built in real time. The most useful thing you can say is "what's another way?" — and then wait. The waiting is the teaching. Watch for: a child who adjusts and tries again instead of giving up or melting down.

11:20–11:35

Handwash / bathroom. Tidy the centers, wash up before lunch.

11:35–12:10
Fixed
Lunch

Calm, social, unhurried. Teachers sit with the children.

12:10–12:25

Handwash / bathroom. After lunch, before heading outside.

12:25–1:00
Outdoor Activity / Play

Short and shaded — it's the hottest stretch of the day. A light second sand visit or shaded water play; move indoors on a hot day.

1:00–3:00
Fixed
Quiet Time

Same ritual as Monday — dim lights, soft music, the same two or three songs. That sameness is exactly why today goes a little easier than yesterday.

3:00–3:30

Wake-up · handwash / bathroom. Lights up slowly, cots away, bathroom and handwash.

3:30–3:50
Fixed
Afternoon Snack

Gentle and low-key — the day is winding down.

3:50–4:20
Manipulative

Kinetic-sand trays with molds, or pattern-making with shells: line them up, copy a pattern, extend it.

4:20–4:35

Cleanup & room reset. The children help — cleanup song. Reset the room for tomorrow.

4:35–4:50

Handwash / bathroom. Wash up before the closing circle.

4:50–5:00
Closing Circle

Begin the "castle dreaming" conversation that plants the week's goal: "On Friday we're going to build a big sandcastle together. What should our castle have? Towers? A moat? Flags?" Jot every idea on chart paper — you'll use this list Wednesday.

5:00–6:00
Combined Active Engagement — Departure

The classrooms combine for departure. Specific handoffs: "Ask Liam what he discovered about wet sand today — he figured something out."

Day3
Wednesday
Building Together
Two sets of ideas, one castle · flexibility goes social.
6:30–8:30

Combined arrival care. All classrooms together — quiet free play and a soft welcome until the Bigs room opens.

8:30–8:50
Opening Circle — Building With a Friend

Review the schedule, practice the attention signal. Introduce today's idea: "Today we build in teams. Building with a friend means two sets of ideas — what do we do when you want a tower and your friend wants a wall?"

Here's the trick good builders use: they don't pick one idea OR the other. They find a way to use both. A tower… on top of a wall.
8:50–9:00

Handwash / bathroom. In from circle, before outdoor play.

9:00–9:30
Outdoor Play · Partner Builds (anchor)

Children build in pairs or trios in the sandbox — a shared deep hole, a tunnel between two diggers, a small castle for two. The real work isn't the sand; it's combining ideas, taking turns, and adapting your plan to fit a friend's.

Teacher's role — coach the negotiations, don't settle them. When two kids stall, ask "how could you BOTH be right?" Materials — sandbox, buckets, scoops, a few shared tools per pair, sun protection.

✦ Flexibility today — the social kind. When two kids want different things, the flexible move is a third idea that uses both. Narrate it: "You wanted a tower, she wanted a wall — and you made a tower ON a wall. That's flexible thinking."
9:30–9:50
Fixed
Morning Snack

Wash up coming in. Chat: "What was it like building with a partner — easy or tricky?"

9:50–10:00

Handwash / bathroom. Wash up after snack, settle toward the craft table.

10:00–10:30
Craft — Flags & Signs for the Castle

Make the props for Friday's showcase castle — decorate paper flags on craft sticks, paint an "Our Castle" sign. Real props for a real event two days away; the kids can feel the build-up.

10:30–10:50
Music & Movement

Summer songs plus a partner movement game — mirror your partner's moves.

10:50–11:20
Centers / Free Choice — Plan Our Class Castle

Bring out the "castle dreaming" chart from Tuesday. As a group, decide what the Friday castle will be: how many towers, a moat or not, what decorations. Let kids vote on features — a real shared plan they'll build Thursday. Kinetic-sand cooperative builds as a satellite center.

11:20–11:35

Handwash / bathroom. Tidy the centers, wash up before lunch.

11:35–12:10
Fixed
Lunch

Calm, social, unhurried. Teachers sit with the children.

Fixed
Afternoon Snack

Gentle and low-key — the day is winding down.

3:50–4:20
Manipulative

Cooperative building indoors — blocks or connectors, built in pairs. The same skill as the sandbox, a different material.

4:20–4:35

Cleanup & room reset. The children help — cleanup song. Reset the room for tomorrow.

4:35–4:50

Handwash / bathroom. Wash up before the closing circle.

4:50–5:00
Closing Circle

Castle countdown: "Tomorrow the WHOLE class builds our castle together. Tonight, dream about what your part will be."

5:00–6:00
Combined Active Engagement — Departure

The classrooms combine for departure. Specific handoffs: "Ask Maya about the tunnel she and her friend connected — they really had to work together."

Day4
Thursday
The Big Build
The whole class, one castle · problem-solving at scale.
6:30–8:30

Combined arrival care. All classrooms together — quiet free play and a soft welcome until the Bigs room opens.

8:30–8:50
Opening Circle — Today's the Day

Big energy. Review the class castle plan from Wednesday's chart. Assign loose, flexible roles — "we'll need diggers, packers, and decorators" — and make clear kids can move between jobs.

We dreamed it, we planned it — today we BUILD it. Our castle. The whole class. Let's go.
8:50–9:00

Handwash / bathroom. In from circle, before outdoor play.

9:00–9:30
Outdoor Play · The Big Build (anchor)

Thirty minutes goes fast, so pre-stage everything before circle — water, buckets, molds, and Wednesday's flags all waiting at the sandbox. That way the whole block is building. The class builds the showcase castle together, following their own plan. You coach and narrate; you help the group solve problems, but you don't build it for them. When the block ends, rope off the castle so it survives to Friday.

Materials — sandbox, plenty of water, buckets, molds, the flags and signs made Wednesday, cones or rope to protect the castle afterward.

✦ Flexibility today — at scale. A big group castle WILL hit a problem — a wall slumps, a tower's too tall. Throw it to the kids: "Our tower keeps sliding. What should the team try?" Watch for the child who offers a new idea instead of giving up.
9:30–9:50
Fixed
Morning Snack

Wash up coming in. Let the buzz carry: "What part are you most proud of so far?"

9:50–10:00

Handwash / bathroom. Wash up after snack, settle toward the craft table.

10:00–10:30
Craft — Decoration Workshop

Finishing touches for tomorrow — paint more flags, sort shells into "decorating treasure" cups, make any last signs. Everything made here gets carried out to the castle Friday morning.

10:30–10:50
Music & Movement

Summer songs, high energy — the kids have plenty to burn off.

10:50–11:20
Centers / Free Choice

A beach dramatic-play corner (towels, sunglasses, a pretend picnic) and kinetic sand. A calmer counterweight to a big-energy morning.

11:20–11:35

Sandcastle Showcase
Decorate, reveal, celebrate · the anchor day.
6:30–8:30

Combined arrival care. All classrooms together — quiet free play and a soft welcome until the Bigs room opens.

8:30–8:50
Opening Circle — Showcase Day

Pure excitement. "Today we finish, decorate, and SHOW our castle." Quick run-through of the plan for the morning.

If the castle didn't survive the night — and sometimes it won't — don't treat it as a disaster. "Our castle needs some repairs! Good thing we're expert builders now. Let's fix it together." A rebuild is the perfect last note for a flexibility week.

8:50–9:00

Handwash / bathroom. In from circle, before outdoor play.

9:00–9:30
Outdoor Play · Decorate + Showcase (anchor)

Carry out the flags, signs, and shells. Finishing touches first, then the Sandcastle Showcase: the whole class steps back together, admires what they built, and names the parts ("that's MY tower"). Take the group photo — this is your shot-list moment. Let it feel like an event.

Materials — shells, flags, signs, the camera staged and ready, sun protection.

✦ Flexibility today — the finish line. If the castle needs fixing or rebuilding, don't rescue it — let the kids problem-solve the repair. A castle that needed a rebuild and got one is a better flexibility lesson than one that stood perfectly.

Each child makes something to take home — a shell craft, or a drawing of the class castle. A small, proud artifact of the first week of camp.

10:30–10:50
Music & Movement

Favorite summer songs of the week — a gentle, celebratory feel.

10:50–11:20
Centers / Free Choice — Beach Celebration

4:50–5:00
Closing Circle

Reflect on the week as a group: "What was your favorite day this week?"

5:00–6:00
Combined Active Engagement — Departure

The biggest handoff moment of the week. Invite parents to peek at the castle if it's still standing; show them photos. Specific, proud handoffs: "Ask Sofia which tower is hers — she'll know exactly." A parent who drives home Friday thinking "that was a real week" is a parent leaning toward staying.

Section 5 · The Lens

This Week's EF Lens — Cognitive Flexibility

One executive-function skill to plan toward and notice this week. (The full EF primer is in the General Planning Guide.)

Why flexibility, and why sand

Cognitive flexibility is the skill of shifting strategy when the first approach doesn't work — trying another way instead of stalling or melting down. Of all the summer themes, Fun in the Sun is the most natural home for it, because sand is a material that constantly requires adaptation: too dry, add water; too wet, it won't hold; collapsed, rebuild it differently. You don't have to manufacture flexibility moments this week — sand hands them to you all morning long.

Your job isn't to teach flexibility as a lesson. It's to notice it and name it when it happens: the moment a child's tower falls and they reach for water instead of giving up. Resist the urge to fix the collapse — the collapse is the curriculum. Ask "what's another way?" and wait.

What flexibility looks like in the children this week

  • A child whose sand shape collapses and tries a different approach — packs tighter, adds water, switches molds
  • A child building with a partner who finds a "third idea" that uses both kids' plans
  • A child who rolls with a change — the castle needs a rebuild — without falling apart
  • A child who offers a new suggestion when the group build hits a problem
Section 6 · Parent Connection

Brightwheel This Week

One intentional post a day — a photo and a sentence or two. That's it. One good moment beats six scattered ones; a firehose makes parents tune out. Grab the photo, adapt the caption.

Section 7 · Before Day 1

What to Have Ready Before the Week Starts

Week 1 has its own prep — beyond supplies. Have all of this staged the Friday before camp begins.

Visual schedule, printed and posted
Picture cards for every block of the Bigs day, at child height. Introduced at the very first Opening Circle.
Attention signal chosen and rehearsed
Decide the words and the response before Monday. The whole team uses the identical one.
Cleanup song + quiet-down songs chosen
Pick them now — the same songs run all summer. Choose ones you won't mind hearing 200 times.
Soft-landing protocol agreed by the team
A calm corner, a small job, a consistent adult — decided before the first child cries on Monday.
A name plan for Day 1
Name tags for the first days, or a deliberate name-game plan. Knowing names fast is the Week 1 priority.
Sandbox stocked + sun protection staged
Fresh sand, buckets, scoops, shells, molds. Sunscreen and hats by the door. Pre-stage it nightly — the outdoor block is only 30 minutes.
Allergy list checked — snacks AND sand-play materials
Some kinetic sands and sensory fillers contain allergens. Check before Monday, not during.
Heat plan for the week
Backup trigger set: >100°F, AQI red, or wind advisory → indoor "Sunshine Studio" (kinetic sand, bubble-wrap art, beach music). The 12:25–1:00 Outdoor Activity is the first thing to cut on a hot day; decide each morning.
