Need a way to work on those numbers 1-20? This file contains 4 different kinds of cards for the game concentration including ten frames, tally marks, base ten blocks and numerals. You can mix and match the cards to make different sets -- you can use the same cards for weeks if you switch out the kinds of cards (they've been color coded to sort them more easily)
Or, use the cards to improve automaticity in math warm ups!
Great work for independent practice or with a buddy at a math station!
