This activity starts off easy and gradually gets harder. The first slide is a drag and drop using the box method. The second slide, has the boxes labeled, but the students need to type the answer (rather than drag) into the box. The last slide has nothing but a box drawn and the question. The student will have to fill in all parts.

**I would normally have the students attach a piece of paper or use a white board to show their work (adding the numbers up).
