To model a whole number times a decimal:
Example 3 x 0.2 =

This is 3 groups of 0.2 so shadein 3 groups of 2 tenths.
Example 3 x 0.2 =

To Model decimal x decimal:
Example 0.3 x 0.5 =

First, shade in the first number vertically.
Example 0.3 x 0.5 =

Second, shade in the 2nd number horizontally.
Example 0.3 x 0.5 =

The area that has been shaded twice is the answer.
Example 0.3 x 0.5 = .15

0.5 x 0.4 = 0.20
