This product comes with three (B&W) differentiated twenty frame mats.
1. Beginner Twenty frame with numbers shown in each frame: To teach what number patterns look like.
2. Twenty frame with no numbers: To begin to teach adding up to twenty.
2. Twenty frame with two blank equation lines: Understanding addends when adding to twenty. And relating the math fact with to ten fact. (ex: 6+7= 13, 10+3=13)
I suggest that you laminate them and you can make them double sided with two of the differentiated mats.
This product can also be used with the "Colorful Ten Frame Mats":
