For curious kids ages 3–11 and the grown-ups who teach them

Curio Kids CrewBig ideas, broken into small pieces.

Five learning tracks that start with the building blocks: how to think, how to move, the shapes nature repeats, the elements everything is made of, and a first handful of ASL. Each lesson comes with a grown-up guide, so you can learn it and teach it on the same day.

The playbook

How kids actually learn

There's no single official playbook for children's learning, but decades of research agree on a short list of things. The Curio Loop below turns them into one repeatable lesson shape, so every video, card and printable follows the same rhythm.

The Curio Loop

Every lesson runs these six steps in order. A full loop takes 10 to 20 minutes; a Short covers the first three and points to the rest.

  1. Step 1Wonder

    Open with a real question a kid would ask.

  2. Step 2Move

    Put the idea in the body: act it, build it, walk it.

  3. Step 3Make

    Draw, sort or build something they can hold.

  4. Step 4Name

    Now give the real word. Three new words, max.

  5. Step 5Share

    The kid teaches it back to someone.

  6. Step 6Return

    Revisit in a few days with a flashcard or new example.

The research behind it

Jean Piaget

Concrete before abstract

Young children reason best about things they can see and handle. Abstract thinking grows later, around 11 and up.

In Curio: every lesson starts with an object, a food or the kid's own body.

Lev Vygotsky

Scaffolding & the "just-right" zone

Kids learn most from tasks slightly beyond what they can do alone, with a helper who steps back as they improve.

In Curio: "I do, we do, you do." The grown-up guide shows where to step in and where to back off.

Jerome Bruner

Do it, see it, say it

Ideas land in three layers: action, then picture, then symbol. His spiral curriculum revisits big ideas at deeper levels as kids grow.

In Curio: Move → Make → Name, and every track has a 3–5, 6–8 and 9–11 level.

Maria Montessori

Prepared environment

Real materials, self-directed choice and activities that show kids their own mistakes without an adult correcting them.

In Curio: printables are self-checking (match, sort, find) and work without a screen.

Reggio Emilia approach

The child as researcher

Kids investigate questions they care about and show what they know in many forms: drawing, building, movement, talk.

In Curio: the Share step lets kids explain however they like, and "Wonder" questions come from real kid questions.

Hirsh-Pasek & Golinkoff

Guided play

Play with a gentle learning goal beats both free play and lecturing when you want kids to learn something specific.

In Curio: every activity is a game with one target idea.

Cognitive science of learning

Retrieval, spacing, dual coding

Recalling an answer strengthens memory more than rereading it. Short reviews spread over days beat one long session. Words plus pictures beat either alone.

In Curio: flashcards, the Return step, and one idea per Short.

Embodied cognition

Thinking with the body

Gesture and movement help kids understand and remember, especially for space, number and science ideas.

In Curio: the Move step is never skipped, and Move Lab is its own track.

Universal Design for Learning (CAST)

Many ways in, many ways out

Offer several ways to engage, take in information and show learning, so more kids can join in from the start.

In Curio: captions on every video, ASL woven in, and printables with pictures and words.

Age bands

Same big idea, three depths. Each lesson lists all three.

Tiny CrewAGES 3–5

Touch it, move it, name it. One idea, lots of repetition.

CrewAGES 6–8

Sort, draw and explain. Two- and three-step chains.

Big CrewAGES 9–11

Predict, test and design. "Why does it work that way?"

Myths to skip

  • Learning styles. Matching lessons to "visual" or "auditory" learners doesn't improve results in studies. Use words and pictures and movement for everyone.
  • Left-brain / right-brain kids. Both sides work together on nearly everything.
  • "Smart" praise. Praise the effort and strategy ("you kept trying different ways") rather than the kid ("you're so smart").
  • Screens teach on their own. Kids learn far more from video when a grown-up watches and talks about it with them.

Screen-smart video

  • The American Academy of Pediatrics has long advised about one hour a day of high-quality programming for ages 2–5, ideally watched together, and avoiding screens other than video chat under 18 months.
  • Every Short ends with an off-screen action ("Your turn: …") so the video sends kids away from the screen.
  • Slow pacing, one idea, real objects. No fake urgency, no cliffhangers built to drive autoplay.

YouTube rules for kids' channels

  • Under COPPA, videos aimed at children must be set to Made for Kids in YouTube Studio. That turns off comments, personalized ads and some features.
  • Don't collect kids' names, photos or emails on the website. Talk to grown-ups in sign-ups and contact forms.
  • Burn captions into every Short. They help pre-readers connect words to sounds and make videos accessible for Deaf and hard-of-hearing viewers.
1FpFirst Principles

Track 1 · Take-It-Apart Detectives

“Big things are made of small things. If you know the small things, you can build anything.”

For grown-ups: first-principles thinking means breaking a problem into the basic facts you know are true, then reasoning up from there instead of copying what everyone else does. Aristotle called them “the first basis from which a thing is known.” Taken all the way down, matter breaks into elements, which is why this track leads into Element Explorers.

Starter lesson · 15 min

What's in a pancake?

  1. Wonder

    “Before this pancake was a pancake, what was it?”

  2. Move

    Ingredient freeze. Call out an ingredient and kids act it: flour falls like snow, an egg curls up and cracks open, milk pours itself out.

  3. Make

    Draw a Take-Apart Tree. Pancake at the top, branches to flour, egg and milk. Then flour → wheat → seed + sun + water + soil.

  4. Name

    Part, whole, made of.

  5. Share

    Kid teaches it back: “A pancake is made of ___. Flour is made of ___.”

  6. Return

    Next day, take apart something new: a crayon, a chair, rain.

You need: one pancake (or a photo), paper, crayons, Take-Apart Tree printable.

What's really going on

Kids already do this. A chain of “why?” questions is first-principles thinking in its natural form. Your job is to keep the chain going instead of ending it.

Say it like this

“Good question. What do we already know for sure?”“Let's break it into pieces.”“I don't know yet. How could we find out?”

Watch for

  • Ending the chain with “because that's how it is.”
  • Giving the answer before they've had a guess.

By age

3–5Take apart real things: a flower, a toy, a sandwich.6–8Take-Apart Trees on paper, three levels deep.9–11Rebuild challenge: “Using only these parts, design a better ___.”
2MvMove Lab

Track 2 · Your Body Is a Machine

“Bones are the frame. Muscles are the motors. Your brain is the boss that sends the messages.”

For grown-ups: movement builds coordination, balance and body awareness (the sense of where your body is, called proprioception). Short activity breaks also help kids refocus. This track teaches the science while getting the wiggles out.

Starter lesson · 15 min

Animal Walk Lab

  1. Wonder

    “How can a frog jump so far? Can you?”

  2. Move

    30 seconds each: bear crawl, crab walk, frog jump. Then flamingo stand on one foot for a count of 10, and switch feet.

  3. Make

    Hand on chest: is your heart fast or slow? Draw it as an animal: “My heart was a ___.”

  4. Name

    Muscle, bone, balance.

  5. Share

    “Which walk was hardest? Which body part worked the most?”

  6. Return

    Repeat next week. Can you flamingo longer than last time?

You need: clear floor space, grippy socks or bare feet, Move & Freeze cards.

What's really going on

  • Muscles can only pull, so they work in pairs. The biceps pulls your forearm up; the triceps pulls it back down.
  • Adults have 206 bones. Babies are born with about 300, and many fuse together as they grow.
  • Cross-body moves (right hand to left knee) get both sides of the body working together.

Say it like this

“Feel that muscle get hard? That's it pulling.”“Balance is your brain and muscles talking really fast.”

Watch for

  • Hard floors and racing. Keep it about noticing, not winning.
  • Using exercise as a punishment. Movement should stay fun.

How much movement?

The World Health Organization recommends kids 5–17 average 60 minutes a day of moderate-to-vigorous activity, and ages 3–4 get at least 180 minutes of any activity spread across the day.

By age

3–5Animal walks and freeze games. Name the body parts.6–8Find the muscle pairs. Count heartbeats for 10 seconds before and after.9–11Levers: why is it easier to lift with a straight back and bent knees?
3ShShapes of Life

Track 3 · Nature's Shape Code

“Nature uses the same few shapes over and over, because each shape is really good at one job.”

For grown-ups: these patterns come from growth rules and efficiency. Shapes that pack tightly, reach far or protect well tend to win. Teaching the job of each shape turns “ooh, pretty” into real science.

Starter lesson · 20 min

Shape Hunt

  1. Wonder

    “Why do bees build hexagons and not circles?”

  2. Move

    Be the shape. Curl into a spiral. Stretch arms and fingers into a branch. Three kids make a triangle; six make a hexagon.

  3. Make

    Shape Hunt walk with the printable. Indoors, press cups into playdough: circles leave gaps; hexagons don't.

  4. Name

    Spiral, hexagon, symmetry.

  5. Share

    “Show me a shape you found. What job is it doing?”

  6. Return

    Pick a Shape of the Week and spot it everywhere.

You need: Shape Hunt sheet, pencil, a walk outside (or a pile of fruit, leaves and shells).

What's really going on

  • Of the shapes that tile without gaps, hexagons hold the most honey for the least wax.
  • Sunflower seed heads usually show spiral counts that are neighbors in the Fibonacci sequence, like 34 and 55.
  • Branching gets the most reach from one start: a tree to sunlight, lungs to air, rivers across land.
  • Small water drops pull themselves into spheres, the shape with the least skin for what's inside.

Say it like this

“What job do you think that shape is doing?”“Where else have we seen that shape?”

Watch for

Real nature is messy. Not every shell is a perfect golden spiral, and it's good to say so.

By age

3–5Find and name: circle, spiral, branch.6–8Shape Hunt with jobs. Fold paper to test symmetry.9–11Count sunflower or pinecone spirals and look up Fibonacci.

Track 4 · The Universe's Building Set

“Everything (you, your snack, the air) is built from tiny pieces called atoms. There are 118 kinds, and we call them elements.”

For grown-ups: an element is a substance made of only one kind of atom. Its atomic number is the number of protons in each atom, and that's the order of the periodic table. Atoms snap together into molecules, the way bricks snap into a build.

Starter lesson · 15 min

Build a water molecule

  1. Wonder

    “What is water made of?”

  2. Move

    Atom huddle. One kid is Oxygen and holds hands with two Hydrogens. “We're water!” Add a Carbon and two Oxygens: “We're the gas you breathe out!”

  3. Make

    Build H₂O from playdough: one big ball (O), two small balls (H), joined with straws or pretzel sticks.

  4. Name

    Atom, element, molecule.

  5. Share

    “Water is H-2-O: two hydrogens and one oxygen.”

  6. Return

    An Element of the Week card on the fridge.

You need: two colors of playdough, straws or pretzel sticks, the element flashcards.

Starter eight

What are you made of? (by weight)

O 65%
C 18%
H 10%

Plus nitrogen 3%, calcium about 1.5%, phosphorus about 1%, and traces of the rest. Most of that oxygen and hydrogen is in water. Every atom heavier than hydrogen and helium was made inside a star.

Watch for

  • Mixing up atom and molecule. Atom = one brick. Molecule = bricks snapped together.
  • Real chemistry demos. Model with food and toys only. “Sodium explodes in water” is a fun fact, not an experiment.

By age

3–5Element names as characters. Build water with playdough.6–8Symbols and numbers for the starter eight. Element bingo.9–11Protons set the number. Find the starter eight on a full periodic table.

Track 5 · Hands That Talk

“ASL is a language you see. People talk with their hands, their face and their whole body.”

For grown-ups: American Sign Language is a complete language with its own grammar, used by Deaf communities across the US and much of Canada. It isn't English spelled on the hands, and facial expressions are part of the grammar. Other countries have their own sign languages; British Sign Language is very different from ASL.

Starter lesson · 10 min, then every snack

Snack-time signs

  1. Wonder

    “How could you ask for more without making a sound?”

  2. Move

    Practice MORE, PLEASE, THANK YOU and ALL DONE with big, clear hands and a matching face.

  3. Make

    Fingerspell your first name with the alphabet chart. Draw your favorite sign.

  4. Name

    Sign, handshape, fingerspelling.

  5. Share

    Ask for a snack using only signs.

  6. Return

    Use the four snack signs at every snack for a week.

You need: a snack, an ASL alphabet chart, and a video dictionary open to check each sign.

First eight signs

HELLOFlat hand starts near your forehead and moves out, like a small salute.
THANK YOUFingertips of a flat hand touch your chin, then move forward toward the person.
PLEASEFlat hand on your chest, rubbing in a circle.
MOREBoth hands in a flat “O”; tap the fingertips together twice.
ALL DONEOpen hands, palms toward you, twist out so the palms face away.
MILKOpen and squeeze your fist, like milking a cow.
HELPThumbs-up fist resting on your other flat palm; lift both together.
FRIENDHook your index fingers together, then flip and hook again.
Check every sign on video first. Written descriptions are a starting point. Good free sources: Lifeprint.com (Dr. Bill Vicars), Signing Savvy, and Gallaudet University's ASL Connect.

Respect notes

  • Name signs are given by members of the Deaf community. Until then, fingerspell your name rather than making one up.
  • Capital-D “Deaf” refers to Deaf culture and identity.
  • Before publishing ASL videos, bring in a Deaf ASL consultant or co-host. It's the right thing to do and it makes the content trustworthy.

Thirty cards for the Return step

Ask the front, let them guess out loud, then flip. Guessing before seeing the answer is what makes it stick. Shuffle tracks together once kids know a few, since mixing topics strengthens memory.
