Find and Erase Shapes.

Can your child make every matching pair disappear? Draw pairs of chalk shapes outside, then let your child erase one with a wet paintbrush, hunt for its match, and erase that one too, building shape recognition and visual attention.

  • Water
  • 1 small cup or bowl
  • 1 dry sidewalk or patio spot
10 min minimum

Fill a small cup or bowl with water and get a paintbrush.
"Find one."
The loop

How play unfolds.

Three-panel sequence showing a grown-up pointing to a chalk shape, a toddler erasing it with water, and the child finding the matching shape.
  1. 01
    Have your child dip the paintbrush in water and paint the first chalk shape with water until it disappears.
  2. 02
    Ask them to find the matching shape.
  3. 03
    Have them paint the matching shape with water until it disappears, then choose another pair and repeat.

Safety Check

  • Wet pavement can become slippery, so keep the walking path mostly dry and stay close while your child moves between shapes.
  • A real paintbrush can become a poking or mouthing risk if the child stops using it as a brush.
Skill spotlight
Visual Matching

Matching same shapes by sight.

This helps your child notice what is the same and different, use shape words in real play, and compare what they see before acting. Those same comparison skills show up in puzzles, blocks, socks, picture cards, and simple "find the same one" directions.

  • •Erasing one shape and then finding its partner gives same/different comparison an immediate purpose.
  • •The wet brush keeps fine motor work visible because each stroke changes the chalk.
  • •Repeating the pair loop helps your child hold one shape in mind while looking around.
Real-world transfer
  • Matching puzzle pieces, blocks, socks, or simple picture cards
  • Noticing shape words in books, signs, and toys
  • Comparing 2 choices before picking one
  • Following short "find the same one" directions

What to say in the moment

Match what you say to what you see.

Prompt ladder
Level 1 (Start)
"Erase this shape, then find the same one."
Level 2 (Keep going)
"You made one disappear, now hunt for its partner."
Level 3 (Stretch)
"Can you point to the match before your brush touches it?"
Level 4 (Extend)
"Let's do one more pair in green chalk."
If your child seems...
What you'd see
Focused
What to do
Say
"You got that one. Find the same shape again."
Add
Ask 1 simple shape prompt after the erase, such as "What shape was that?"
Extend
Let your child choose which visible pair to erase next.

Make it easier

Younger end
  • -Draw the next round with bigger shapes so the match stands out faster from across the patio.
  • -Walk your child to the first shape instead of sending them out to search alone.
  • -Let matching be the only job and give the shape name yourself after the brush starts moving.

Make it harder

Older end
  • +Ask your child to point to the matching shape before erasing the first one.
  • +Start each turn from the water cup so your child has to remember where the partner is while walking back out.
  • +Add 1 extra pair of a shape your child already knows and place it farther from the others.

If it's not working

If you see
If child ignores it
Start with only 1 pair of circles and erase one yourself. Say, "Your turn to make the other circle disappear."
If you see
If child misuses it
If the brush becomes a poke, splash, or throwing tool, hold the cup yourself and offer one dip at a time.
If you see
If child gets frustrated
Drop the naming demand. Say the shape for them and ask for the match: "This is a square. Can you find another square?"
