Ask students how they can record their solutions on
paper. Encourage them to explore different methods.
Students can record their solutions using word
descriptions, drawings, diagrams, blueprints, number
sentences, or some combinations of these methods.
Ask students to select two of the shapes that they
constructed and record them on the Make Shapes
with Cubes pages using whatever recording method
they choose and number sentences. See Figure 4.
The 4-cube models can be difficult for students to draw. Try
using a camera to capture the various models. This may even
allow you to refer back to these buildings in future lessons.
Use the Make Shapes with Cubes pages and the Feedback
Box in the Student Activity Book to assess students' abilities
to recognize that different partitions of a number have the
same total [E1]; apply the properties of addition (e.g., commutative, associative) to write number sentences that
represent the volume of a building [E3]; make connections
between a building of cubes and number sentences [E4];
identify shapes that are the same size and shape [E5];
recognize that different shapes can have the same volume
[E6]; count and add cubic units to find volume [E8]; and
show work [MPE5].
