Pick a common word your child uses frequently — "big", "happy", or "walk" are great starting points. Challenge them to find as many different words that mean something similar as they can. Use a picture book, the room around you, or your own suggestions to model new words: huge, enormous, gigantic; pleased, joyful, delighted; stroll, march, tiptoe. Each new word earns a tally mark on a piece of paper, building a visible record of their growing word hoard.

Best for this moment

for calmer, lower-pressure moments, especially when you need an indoor option.

Parent tip

Set out paper and pencils before inviting your toddler in so the first minute feels smooth.

What success looks like

A good outcome is a few minutes of engaged play, some back-and-forth with you, and a small sign of progress in cognitive skills.

Instructions

Get ready
  • Choose a target word together — start with an adjective your child uses a lot.
  • Write the word at the top of a piece of paper and explain you're going to find its "word family."
  1. Choose a target word together — start with an adjective your child uses a lot.
  2. Write the word at the top of a piece of paper and explain you're going to find its "word family."
  3. Ask, "What's another word for big?" and accept all ideas warmly.
  4. Add your own suggestions, using each in a fun sentence so meaning is clear.
  5. Act out any words that have a physical quality.
  6. Count the synonyms together and cheer for the total.
  7. Challenge: can they use one new word correctly before bedtime?
  8. Next session, pick a new target word and try to beat the previous score.

Why it helps

Vocabulary breadth at age three is one of the best predictors of reading comprehension at age eight (Hart & Risley, 1995). Teaching synonyms explicitly helps children understand that language is flexible and nuanced, encouraging them to reach for precise words rather than defaulting to high-frequency standbys. Acting out words adds a kinaesthetic memory hook that helps new vocabulary stick.

Variations

  • Act out each synonym physically — tiptoe vs stomp vs stride.
  • Draw a picture for each word cluster and display them on the fridge.
  • Play in reverse: you say a big word and your child finds a simpler one they already know.

Safety tips

  • Celebrate every attempt — approximations are fine at this age.
  • Avoid correcting pronunciation during the game; model the correct form naturally in your next sentence.
  • Keep sessions to five minutes or less — vocabulary games lose their sparkle if they drag on.

When to pause and seek extra support

Stop if your child becomes distressed, unsafe, or consistently frustrated by the activity. If play, behaviour, or development worries keep showing up across settings, check in with a qualified professional.
