Decomposing Numbers – Matchup Activity

Teach Starter Publishing
PDF | 12 pages | Grades: 1 - 2

A set of decomposing number cards to create number sentences when grouping in tens and ones.

Use this teaching resource to help students understand the decomposing of numbers and the importance of grouping in tens and ones.

Students decompose a range of two-digit numbers by connecting them with their corresponding ‘tens’ and ‘ones’ cards. You may want to have your students use Base-10 blocks to create the number first before finding the matching number cards. Then connect to expanded form by having your students use the addition and equal sign cards to make a number sentence.

This activity is great to use as a math center activity during your place value unit.

A page of blank cards has been included with the download for you and your students to create your own number cards.
