Looking Through the Algebraic Lens

Work with rectangles to find generalizations for adding and subtracting odd and even numbers! Upper graders are give some 2" by" and some "2 by with a tail" shapes to small groups. They identify some examples of shapes that represent odd numbers and some that represent even numbers. Students work in groups to find patterns when they add or subtract the numbers the shapes represent.
