Decomposing Numbers Using Place Value

Decomposing numbers into place value means breaking down a number into its constituent parts based on its place value in the number system. Understanding this allows children. to understand the contribution of each digit to the overall value of the number.

Print, cut out, and laminate a class set of the decomposing cards and store them in a zip-lock bag. Students, individually or in small groups, connect the number cards with the addition and equal sign cards to create a number sentence.
