Students use the Kidspiration program to model multiplication and division fact families. Each rod represents a different number on the grid. For instance, the yellow rod covers 5 squares. In the example above, the student recognizes that there are six groups or six rows of yellow rods. Each rod covers five squares. 6 x 5 = 30 squares covered. They can also reason that five squares are covered in each of six rows. There are 30 squares covered, or 5 x 6 = 30. The models also show the inverse, division. There are 30 squares covered in six rows. There are five squares covered in each row. 30 ÷ 6 = 5. There are 30 squares covered and each row has five squares. There are are six rows, or 30 ÷ 5 = 6
