This is a common core aligned Smart Board activity that contains 26 pages of interactive addition and subtraction for the Smart Board. This product may be used during whole-group math instruction or in a math center. The students will love the interactive "candy buttons" that are either to be dragged or tapped to show the correct computation for the page. After the work is complete and written in the box provided, students can tap the rolling pin to fade away and reveal the answer. This allows students to self-correct independently during a math center. This product may be printed to accompany the lesson or math center.
