What kids do

“Write the numbers in order from the smallest to the biggest.”

Teacher tip

Let kids write each number on a sticky note and slide them into order first.

How to use it

  • Let early counters use real cubes on top of the pictures.
  • Count out loud as a class first, then let kids count in a whisper voice on their own.
  • Do the first problem together under a document camera, then let kids finish on their own.

Watch for

Kids who recount the whole group instead of counting on. Ask, “You already know there are 5 here. What comes next?”

Talk about it

  • Did you count by ones, or did you see a group right away?
  • Which problem was the hardest? What made it hard?

Take it further

Play “I’m thinking of a number” with clues like more than 12 and less than 15.
