#### Your students will use these activity sheets to help them master the skills behind operational addition and subtraction. Each sheet contains a given number (the target sum/difference) within a central circle, and your students must come up with three different addition equations and three different subtraction equations that result in the given number. The target numbers range from 10 to 209. No answer keys have been provided for these activity sheets for instructors, as each equation may vary widely by student.
