Perfect! Not too big and perfect size for desk. Great for fingers to count on.

These are very nice for children learning to add and subtract. I learned with number lines and thought it would be helpful for my granddaughter. I did not read that there were 30 in the pack so maybe take note of that. Great value for the money.

I laminated to make more durable, but don’t need to. Dry erase marker works well. Great as a math manipulative.

I had these laminated at my school and they are fantastic. My students got a lot of use out of them and it was a great tool for them to have.
