DescriptionIn this clip, Stephanie and Dana work on recording their solution to the Towers Problem, introduced in the first clip in this series. As Dana finishes her recording her towers solution individually, Stephanie works on recording their solution on a large sheet by coloring in towers to represent the towers they have built. Stephanie remarks that it is easier to first color in all the red blocks and then color in all the blue ones and proceeds to do so. When Dana is finished recording her individual solution, Stephanie tells her to color in blue all the blocks that she left blank. Stephanie then realizes that although there should be one that is all blank, she has mistakenly colored it, so she corrects her mistake by crossing out the all red tower and drawing a blank tower next to it. The girls finish representing their solution on the large sheet.
