Write About the Math
How many bags of concrete does the builder need?¿Cuántas bolsas de concreto necesita el constructor?
Say your answer to a partner first. Then write it, using at least two of these words:
Model: We use both bases because the top and bottom are different lengths. — Students explain a trapezoid has two parallel sides of different lengths, so using only one would over- or under-count the area; strong answers mention averaging the bases.
