Students compose an addition equation based on colored cubes and solve for the sum. They use equations to show that there is more than one way to represent a total. Students then solve addition equations without cubes shown
A. Count two addends and determine the total
B. Determine total number of objects and determine its two addends
C. Use the + and = signs in an equation
D. Identify addends and sum in an equation
E. Compose an addition equation based on a picture
F. Represent objects with cubes
H. Solve addition equations
