These 20 task cards are a great way to check your students' understanding of the concepts of addition and subtraction. There are tables, word problems, missing number problems, and even problems relating to the properties of addition and subtraction. (Our textbook refers to any ideas related to subtraction as "subtraction rules" so that is the term used here. Your students could certainly be successful with these cards without using that terminology.
These cards are great for work stations or centers, independent work, test prep, or playing Scoot. I hope you find this product useful with your students. Please leave feedback.
