What kids do

“Start at the first number. Count on by ones. Write the next numbers in the train.”

Teacher tip

The jump from 39 to 40 is where kids get stuck. Practice the “nines” together 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

Set up a counting jar at the center and have kids estimate before they count.
