Write About the Math
How many more cubic inches does the large box hold than the medium box?¿Cuántas pulgadas cúbicas más tiene la caja grande que la caja mediana?
Say your answer to a partner first. Then write it, using at least two of these words:
Model: Volume measures space in three directions, so you need length, width, and height. — Students explain that volume is three-dimensional, so all three edges (length, width, height) are needed; two measurements only give area of one face.
