“Room Room Room” always equals 36.
Some of the rooms are missing one or two
values. In this exercise, students will learn 1 kg 9 kg 4 kg
how to “solve” for these missing values. 12 4 1

Have students locate the only complete path

2. Build Understanding
Remind students that the man said products that result from multiplying three numbers in the connected
rooms are always the same.
Each time students find a correct answer, fill in the room with that correct answer; the correct answers for
the remaining paths depend on the previous answers.
