These place-value cards will help your kids understand the number system. After preparing these (directions in download), use them to label sets of items that you count together in class or small groups. For example, after sorting and counting toothpicks use the numbers to label the groups; to construct 9823, start with 9000; place the 800 on top, followed by 20 and 3. Then align the right sides.
I hope you and your kids LOVE and enjoy using these.
