Jenny uses a 10 by 10 decimal grid to show the product of 0.6 x 0.2. How could Jenny use the model to find the product?

• Count the number of squares where the shading overlaps.

• Count the number of shaded columns.

• Count the number of shaded rows.

• Count all the shaded squares.

• 0.2 x 0.04 = 0.2

• 0.2 x 0.2 = 0.4

• 0.2 x 0.2 = 4

• 0.2 x 0.2 = 0.04

• The yellow is the product.

• The blue is the product.

• The overlapping of yellow and blue is the product.

• The overlapping of yellow and blue is the quotient.
