This is a set of three math activities for students to practice addition and subtraction skills. For the first activity, students will be given a number. Then, they will choose an M&M candy and follow the code in order to add or subtract. For the second activity, students will roll a die or dice (teacher's preference) and then choose an M&M candy. Students will follow the code and record their answers in a chart. The third activity is a variation of the first. This is a great way for students to practice adding and subtracting 1, 10 and 100 which reinforces mental math and using the hundreds chart. This can be used as a center activity. Students are also able to record their number sentence for each problem they create. These activities can be easily differentiated.
