This is a composing and decomposing activity that is great for introducing foundations of numbers to your students as well as a reinforcement in stations throughout the year. Students will be given a picture of base-10 blocks or place value disks. Then they will compose that number by filling in a place value chart and writing it in standard form. Students will also be decomposing numbers from standard form by filling out the place value chart and then representing the number by drawing base-10 blocks or place value disks. This activity also comes with two reference charts for the student’s math interactive notebook, answer recording sheet, and key. This is set one.
