Great for guided math centers or independent centers.
Print, laminate, and cut out the gumballs. Then you have a counting math center. These mats are self checking for the students to check his/her work. After the students count out the gumballs onto the counting mat, then he/she can transfer the gumballs to the 10 frames mat and flip over the counting mat to check his/her answer.
The counting mats start at 1 and go up to 30.
