Decomposing 3-Digit Numbers - Match-Up Cards

PDF | 8 pages|Grades: 1 - 2

A set of decomposing 3-digit number cards to help students identify the place value of hundreds, tens, and ones.

Use this teaching resource during math group activities to help students understand the decomposing of numbers and the importance of grouping in hundreds, tens, and ones.

Students decompose a range of three-digit numbers by connecting them with their corresponding ‘hundreds’, ‘tens’, and ‘ones’ cards.

Print, cut out, and laminate a class set of the decomposing cards and store in a zip-loc bag. Individually, or in small groups, students connect the number cards with the addition and equals sign cards to create a number sentence.

A black and white version of this resource is also available.
