Materials Needed

  • Colored blocks, Duplo bricks, or Lego in 2-3 colors
  • Snack items in 2 types (goldfish crackers and blueberries, or cheerios and raisins)
  • Stickers in 2-3 shapes or colors
  • A blank strip of paper and a glue stick (for sticker patterns)

Readiness Indicators

  • Can identify and name colors
  • Can repeat a simple sequence of claps or sounds
  • Shows interest in things that repeat (stripes on a shirt, tiles on a floor)

Learning Objectives

  • 1.Recognize a simple repeating pattern (ABAB)
  • 2.Predict what comes next in a pattern
  • 3.Create an original pattern using objects or body movements

Patterns All Around

Overview

Patterns are the backbone of every algorithm ever written — but long before code, children encounter patterns in clapping games, floor tiles, day and night, and the stripes on a bumblebee. This lesson helps children see patterns, predict what comes next, and build their own. It is the most foundational computational thinking skill, and it requires zero technology.

Background for Parents

A pattern is anything that repeats in a predictable way. For toddlers, we start with the simplest kind:

  • AB pattern: red, blue, red, blue, red, blue...
  • ABB pattern: clap, stomp, stomp, clap, stomp, stomp...
  • ABC pattern: circle, square, triangle, circle, square, triangle...

The key insight is prediction: once a child can look at a sequence and tell you what comes next, they understand the rule that generates the pattern. That's the same mental move as reading a loop in code.

Don't rush to complex patterns. An AB pattern that a child truly owns — can spot it, extend it, create it — is worth more than an ABC pattern they're just copying.

Lesson Flow

Opening: Pattern Hunt (5 minutes)

Walk around the room (or look out the window) and find patterns together. Point them out:

  • "Look at the tiles on the floor — white, black, white, black. That's a pattern!"
  • "Your shirt has stripes — blue, white, blue, white."
  • "Day, night, day, night — even the sun makes a pattern!"

Ask your child: "Can you find a pattern?" Give them time. If they point at something that isn't a pattern, say "That's interesting! A pattern is when the same thing happens again and again." Then point at another clear one.

Core: Build a Pattern (10 minutes)

Step 1: You build, they watch.

Line up blocks: red, blue, red, blue, red...

Say: "Red, blue, red, blue, red... What comes next?"

Pause. Let them answer. If they say "blue!" — celebrate. If they grab a green block, gently say "Let's look at the pattern again: red, blue, red, blue..." and point at each one.

Step 2: You start, they finish.

Lay out: red, blue, red, blue. Push the pile of blocks toward them. "Can you keep going?"

Step 3: They build, you guess.

Say: "Now YOU make a pattern, and I'll try to guess what comes next."

This is the critical step — creating a pattern is harder than copying one. Accept whatever they make. If it doesn't repeat, ask: "What's the rule? Tell me your pattern." Sometimes a 3-year-old's "pattern" is red, red, red, red. That's actually a valid pattern (AAAA). Name it: "Wow, all red! Your rule is: always red."

Practice: Snack Patterns (3 minutes)

Line up snack items in a pattern on a plate: cracker, blueberry, cracker, blueberry.

"Look, I made a pattern with your snack! Can you keep it going?"

Let them extend the pattern. Then they eat it. Learning that you can eat is highly motivating.

Closing: Body Patterns (2 minutes)

Do a clap pattern together:

  • Clap, clap, stomp. Clap, clap, stomp. ("What comes next?")
  • Pat head, pat tummy. Pat head, pat tummy.
  • Make up silly ones: hands up, tongue out, hands up, tongue out.

End with: "Patterns are everywhere. Let's keep finding them today."

Assessment

Not a test — just things to notice:

Skill What to Watch For
Recognition Can they point out a pattern you didn't show them?
Prediction Can they correctly say what comes next?
Extension Can they continue a pattern for 3+ cycles?
Creation Can they invent a new pattern (even a simple one)?
Naming Can they describe the rule? ("It goes red then blue then red then blue")

If your child can do the first two, this lesson landed. The rest will come with repetition.

Adaptations

  • Younger (18-24 months): Stick with AB patterns only. Use large objects they can grab. Do it entirely as a shared activity — hand over hand. Clapping patterns work better than objects at this age.
  • Older (3-4 years): Try ABB (red, blue, blue, red, blue, blue) or ABC patterns. Add a "pattern breaker" game: build a pattern with one mistake hidden in it — can they find the mistake?
  • Nonverbal children: They don't need to say "blue" — pointing, grabbing the right block, or placing it in line all count.

Going Deeper

Once AB patterns are solid (days or weeks later — no rush):

  • Growing patterns: 1 block, 2 blocks, 3 blocks... (this connects to early math)
  • Sound patterns: Use a pot and spoon. Tap, tap, pause. Tap, tap, pause. Can they continue?
  • Story patterns: "Going on a Bear Hunt" and similar repetitive books are pattern literature. Point it out: "The words repeat! That's a pattern in the story."
  • Music: "Twinkle Twinkle" verse, chorus, verse, chorus. "Head Shoulders Knees and Toes" repeats the same pattern faster each time.
