Clue: Explain why the volume of a rectangular prism can be found by multiplying its length, width, and height.
The length and width tell how many unit squares are on the base.
The height tells how many layers there are.
Sentence frame: “The base contains ______ unit squares. There are ______ layers, so the volume is found by ______.”
Visual model: base area × number of layers = volume.
Correct response: The base contains length times width unit squares. Each layer has that many cubes, and the height tells how many layers there are. Therefore, volume is found by multiplying length, width, and height.

Clue: Which expressions are equivalent to
A.
Break apart 42 into
Break apart 562 into
Each part must keep its place value.
Use color coding:
562: 500, 60, 2
42: 40, 2
Check that every part of one factor is multiplied by the needed parts of the other factor.
Work:
A breaks apart 42 into 40 and 2.
B is not equivalent because it uses 4 instead of 40.
C breaks apart 562 into 500, 60, and 2.
D breaks apart both factors completely.
E does not represent 562 because it leaves out place values.
Correct response: What are A, C, and D?
