This is a Smart Board presentation that I created. I made it to use while teaching my class about tape diagrams (tape models) for 2-digit addition and subtraction for the first time. I used the EngageNY website as a spark (2nd grade, math module), but the work herein is entirely mine.
I tried to make the concept very visual and "manipulate-able" for teacher and student to use on the Smart Board, giving examples and guided practice.
There are some places where I have a yellow dot. The yellow dot is a prompt for the teacher to tap the Smart Board in that spot and other visuals or text will fade in. On a few slides I left my ink markings, which you can clear.
