How to use this review

  • Do the review over two or three short sittings. Young children learn best in short bursts. Stop while it's still fun.
  • Let your child use fingers, toys, a ten frame, or real coins. Using tools is part of Kindergarten math.
  • Read every question aloud. Your child answers by saying, pointing, counting, or showing.
  • After an answer, ask "How did you know?" Listening to their thinking tells you a lot.
  • Note which section was tricky, then go back to that lesson's activity.

For parents and teachers

Use mistakes to choose what to revisit. Each review section matches one lesson.

  • Skips or mixes up numbers when counting out loud, or always starts at 1: revisit Counting in Order. Sing counting songs and play the rocket blast-off game.
  • Gets a different number each time they count the same group: revisit Touch and Count: One Number for Each Thing. Move each item to a "done" pile.
  • Counts again when asked "How many?", or thinks spread-out things are more: revisit How Many? The Last Number Tells Us.
  • Counts every object even in groups of 2 or 3: revisit Quick Look: Seeing Small Numbers. Play flash-and-hide and dice games.
  • Can't match a numeral to its group, or mixes up 6 and 9: revisit Numerals and Numbers All Around Us. Go on a number hunt.
  • Writes 41 for fourteen, or can't say one more or one less up to 20: revisit Numbers 11 to 20. Build teen numbers with a full ten frame and some more.
  • Picks the longer row or the bigger objects as "more": revisit More, Fewer, or the Same. Line up and match.
  • Makes wild guesses, or won't guess before counting: revisit Good Guesses: Estimating and Checking. Use an estimation jar.
  • Unsure how many are hiding, or how many more make 10: revisit Making Numbers to 10. Play shake and spill.
  • Counts from 1 for facts like 2 and 3, or can't use 3 + 2 = 5 to find 5 − 2: revisit Number Facts to 5. Play finger flash and hide-in-the-cup.
  • Adds when things go away, or can't act out a story: revisit Adding and Taking Away Stories. Use toys on a story mat.
  • Shares unevenly or gives the leftover to one person: revisit Fair Shares: Sharing Equally. Deal out "one for you, one for you".
  • Mixes up coin names, or thinks the bigger coin is worth more: revisit Canadian Coins and Cents. Use the hands trick: nickel = 1 hand, dime = 2 hands.
  • Counts toonies as 1 dollar each, or can't make $5 or $10 different ways: revisit Loonies, Toonies and Bills to $10. Play farmers' market store.

Mistakes are a normal part of learning at 4 and 5. Kindergarten children grow at very different speeds. Praise effort and explaining, not only right answers.
