Dear Teachers,
Thank you for your purchase of the Adding and Subtracting One and Ten Chart. Developing mental math skills in children and helping them understand the patterns found in math is a stepping stone to faster, more accurate problem solving. It is my desire that these scaffolded sheets will help your students grasp the concepts of adding and subtracting tens and ones from any given number through successful repetition.
In this set of sheets I have included 99 and 100 reference charts
