Middle schoolers add, subtract, multiply, and divide rational numbers. They find the square and the cube of numbers. They create a game incorporating computation on rational numbers. Everyone works together to write and evaluate expressions. Note: the associate video is only available via purchase, but the other activities hold enough value to support the instructional activity without it.
