Here is a rectangle that has been partitioned into four smaller rectangles.

Choose a sub-rectangle whose area, in square units, matches: (0.4)*(0.6)

Here is a rectangle that has been partitioned into four smaller rectangles.

Choose a sub-rectangle whose area, in square units, matches: 3*2

Here is an area diagram that represents (3.1)*(1.4)

Find the areas of sub-rectangle A.

Here is an area diagram that represents (3.1)*(1.4)

Find the areas of sub-rectangle B.

Here is an area diagram that represents (3.1)*(1.4)

What is the area of the 3.1 by 1.4 rectangle?

Draw an area diagram to find (0.36)*(0.53). Label and organize your work so that it can be followed by others.

(2.5)*(1.4) = ?

(0.64)*(0.81) = ?

Complete the calculations so that each shows the correct sum or difference.
