Children will love working with numbers with these twenty frame counting mats. There are 52 mats in this set that will be useful in developing a sense of 20 and helping children to work out addition and subtraction problems. Each mat has colorful pictures to draw interest and may go along with a theme being studied in class. There are a lot of seasonal and holiday mats. To get a list of the 52 pictures on the mats, please open and view the Preview page. For additional resources, please visit my store - Terri's Teachables.
