What kids do

“Cut out the numbers. Is each number less than 50 or more than 50? Glue it where it belongs.”

Printed on the sheet:

  1. Look at the tens digit first. 4 tens or fewer is less than 50.

Teacher tip

Use a hundreds chart to show numbers near 50.

How to use it

  • Have kids sort the cards on their desk before gluing anything.
  • Check the sort quickly before kids glue.
  • Keep a few copies in an early finisher bin so they are always ready.

Watch for

Kids who glue too soon. Have them check the sort with a partner first.

Talk about it

  • Can you think of one more thing for each group?
  • What was the trickiest part? How did you get past it?

Take it further

Have kids add a card of their own to each group.
