Task# Grass Seedlings

Illustrative MathematicsVaries

For the sake of this commentary, let be the height of Rual's seedlings (of course students do not need to use a letter to represent any number in this task). Student must compare the size of each of two products to one factor on the basis of the other factor without performing any computations. The wording ' times as tall' may be a clue to students that multiplication is the relevant operation.
