Help your child learn about subtraction during their next meal or snack time with this subtraction place mat! There are lots of subtraction equations with answers on the chalkboard to learn and study. The subtraction table place mat begins with 1-1=0 and goes up to 23-12=11. On the back side of the place mat, kids are challenged to answer subtraction questions. They can write their answers on the place mat with a water based marker. Little number crunchers can even make up some of their own subtraction questions in the blank equation spaces. This place mat offers a delightful way for children of all ages to master a new subject and for adults to brush up on an old one. A fantastic way to practice subtraction while eating a good home-cooked meal!
