2 . Assemble the Soma Cube pieces given on the left to make the figure 2. Have students solve the four puzzles.
These problems involve visualization as well as
on the right. actually forming the figures. They will help
students begin to make the connection
What you need: Colored Pencils between the three-dimensional figures and their
representation as two-dimensional drawings.

where each Soma Cube piece belongs in the
B large figure.
A B A For these problems, they can use a trial-and-

smaller figures and try different ways of fitting
them together until they form a piece that
matches the illustration.

Trial-and-Error Method
1. Select one piece from the left column.
2. Place it in the position you think will help form the figure on the right.
3. Try to fit the other piece from the left column so it forms the figure on the right.
4. If the figure you formed does not match the figure in the book, take apart the figure.
5. Rotate the piece you selected first so it is in a different position.
6. Try to fit the other piece so it forms the figure on the right.
7. Repeat this process until you have created a form that matches the large figure.
