Comparing Numbers Using Number Cards & Ten Frame
Cards Number-Guessing Game Using Counters
Fun Ways to Learn Greater/Less Than Comparisons and Composition/Decomposition of Numbers
As effective tools for helping young students acquire number sense and knowledge about number structure, “counters,”
“ten frame cards,” and “number cards” are provided, in addition to math blocks. There are two particular activities that
help students acquire an understanding of numbers while having fun. The first is a game that concerns greater/less than
comparisons of numbers using the number and ten frame cards. The second game uses the counters to facilitate learning
composition and decomposition of numbers.

Students can gradually learn ways of communicating ideas mathematically!
For the “Card-turning Game,” students move from the concrete to the abstract (the numbers) in the following steps:
1
using only ten frame cards
2
using ten frame cards and number cards

3
using only number cards
