K 1 2 3 4 5 A B

In this activity, Mr. Greenman's class illustrates the algorithm for dividing one fraction by another. The assumption throughout the activity is that the yellow hexagon is equal to one whole. The following relationships to the hexagon are then true:
Triangle = 1/6
Blue rhombus = 1/3
Red Trapezoid = 1/2

Indicator: 6.6.5.1
add, subtract, multiply, and divide with decimals and fractions, including mixed numbers, expressing answers in simplest form.

In the example above, the student starts with the red trapezoid which represents 1/2. The student divides the trapezoid by 1/6, represented by the triangle. When the original red trapezoid is divided by the triangle, the result is 3 triangles. The computation shows the same answer.
In the example above, the student starts with 1 2/6. The student wants to divide by 1/3 (the blue rhombus). You can imagine: how many of the blue rhombuses will fit into1 2/6? The answer is 4, which is also shown with the computation.
