Each page holds a riddle like: “Your pet lizard has escaped and you’ve got to find him right away because your parents’ guests are due to arrive in thirty minutes! Use the clues to draw a path to your lizard’s hiding place.” The grid holds pictures of possible hiding places and to figure out which item he’s hiding behind, you need to solve the addition problems. Each problem has the form 4 + __ = 8 (W). Using the missing number and directional cues (N, E, W, S) found in parentheses as above, you start at the black star in the grid and travel the appropriate number of spaces in the direction given for each problem.
