This product is actually 2 activities. In each activity, students complete 12 stations using the Pythagorean Theorem. Each station has a picture of a right triangle, drawn to scale in centimeters. Students find the missing side length using the Pythagorean Theorem. Then students use a centimeter ruler to "check" their answers. The first activity requires students to find the missing hypotenuse of the right triangle. The second activity requires students to find the missing leg of the right triangle.
