This is the fourth in a series of learning numbers. They range from numbers 1-10, 20s, 30s & 40s, 50s & 60s, 70s & 80s, and 90s to 100. I used these in a station. There is the number that they can trace, then they can illustrate the number on a ten frame, and finally they can trace the word. I put them in sheet protectors and had my students use a dry erase marker.
