The pentominoes in Group 3<br />
lend themselves to creating puzzles with<br />
fixed digits. This allows students to place number tiles in the remaining<br />
squares, either to discover the <strong>algebraic</strong> pattern that exists or to reinforce<br />
the algebra developed.<br />

The Pentomino puzzles<br />
on pages 97 to 100 provide for open-ended<br />
solutions. As in the examples above, write various numbers in the<br />
squares for a and c. Let students provide the missing digits. Discuss<br />
numbers that will and will not work.<br />
