This is a great activity to practice comparing numbers up to 20. This center can be done different ways. It can be done as a group at a center or students can work on it individually at the center.
Students will be given a set of cards with two different sets on it. They need to count the objects in each set and circle the set that is greater.
Then as a follow up activity, they can complete the worksheet that is included!
This activity goes along with the Common Core Standard K.CC.6.a.
