Place Value Disks are a great way for students to work with non-proportional models of numbers. You can use them with a place value chart to represent numbers to 1200 (for second grade) or higher. With a little prep at the beginning of the year, each student can have a set of disks to use throughout the year as you introduce higher and higher values.
Can be printed in color or B&W.
TEKS that cite using place value disks in grades 1-3:
1st: 1.2B, 1.2C, 1.2E, 1.3A
