This PowerPoint was created as part of the Math Tool Box lesson series. Its purpose was to model an efficient subtraction strategy for those "hard" subtraction facts that second graders usually struggle with. Sneaky, Sneaky, Sue also has a chant that goes along with the PowerPoint. Students were then given a worksheet with a variety of subtraction problems on them. They had to draw a sneaker around the problems that would fit the Sneaky, Sneaky, Sue strategy and then solve those problems.
