Students learn to use the multiplication and equal signs to replace the statement "X groups of X make X" with an equation. They determine whether or not a multiplication expression matches a model of real-world objects
A. Solve and re-write repeated addition equations
B. Complete statements describing equal groups and their totals
D. Express multiplication equations based on a model
E. Solve and express multiplication equations based on a model
F. Compose and solve multiplication equations based on a model
G. Multiply based on a model of objects in rows
H. Compose and solve multiplication equations based on an array
I. Compose expressions and equations based on a model
