"CJ's Clues" shows how multiplication problems can be written vertically.It is again shown that each equation is both an addition and multiplication problem, but there are no longer picture guides. Six more problems are presented on flags atop the tops of towers. Ratso and CJ are playing capture the flag.The next activity is similar to the first, but the premise is a scavenger hunt to find gems hidden by the princess.At the end, CJ declares he won by catching 16 fish at once, and readers are instructed to circle the equation that equals 16.

In each equation, the groups of fish are shown and presented as an addition problem, then translated to a multiplication problem. There are three multiplication problems to solve and one example problem. In order to determine the winner, readers must circle the logs with odd numerals, which CJ can hop across, and put an X on the logs with even numerals, which Ratso can traverse. There are twelve inequalities in all, and in three inequalities, two equations must be solved first to determine the numbers to be compared. Readers must solve inequalities on the logs.

CJ and Ratso must complete a moat-crossing contest.

There are five inequalities to solve, but in each problem, readers must first solve two math equations to find out what numbers they're comparing.

Ratso and CJ are in an eating contest, and the reader must determine who has eaten the most.

Each math riddle specifies whether the number is even or odd, one number it is greater than, and one number it is less than. To determine how far CJ's and Ratso's rocks fly, readers must answer their math riddles, eight in all.

"CJ's Clues" explains the terms "greater than" and "less than".

This is the first activity about inequalities that uses numbers exclusively with no pictures. To collect the scarves, readers must answer with the correct symbol. The scarves have mathematical inequalities on them.

To thank CJ and friends for their help, the princess throws them ten scarves.

As a bonus, readers can find which tree has the most and least apples. The first one is already done as an example. Readers are instructed to draw apples on the trees and determine which tree in each set has more apples.

The cook is making pies for the eating contest.Readers must determine in six instances who has collected more rocks. Edison and one of Ratso's henchmen (which here look like normal-sized mice while Ratso is human size) are collecting rocks for the catapult contest.As part of the first tournament contest, a flower-picking contest, readers must determine in six instances who has picked more flowers, CJ or Ratso. "CJ's Clues" explains the greater-than and less-than symbols, though uses the term "bigger".Still helping the princess, readers must draw lines connecting medals with odd numerals to a gold chest and lines connecting even numerals to a silver chest.To help the princess get ready for the tournament, readers must color the banners with even numerals on them. "CJ's Clues" explains the concept of odd and even numerals.
