My first graders love using task cards as a math center. It is a fun and interactive way for children to practice many skills. In my classroom we use task cards in several different ways. A class favorite is when I place the cards all over the room and students go on a hunt answering the different questions using their recording sheet. Students love to be detectives and find all of the numbers/answers. We also use task cards in math centers as well as these are great for early finishers.

In these task cards, students will decompose numbers (or expand numbers) to help understand the true value of each digit. This set includes: 28 task cards, student recording sheet, answer key to help make grading easier, and an activity that allows for teachers to better gauge student understanding of this number concept.

This center is aligned with the common core: K.NBT.A.1, 1.NBT.B.2

Understand that the two digits of a two-digit number represent amounts of tens and ones. Understand the following as special cases:
Compose and decompose numbers from 11 to 19 into ten ones and some further ones, e.g., by using objects or drawings, and record each composition or decomposition by a drawing or equation (e.g., 18 = 10 + 8); understand that these numbers are composed of ten ones and one, two, three, four, five, six, seven, eight, or nine ones.
