CA Standards
AF 1.3, MR 2.3
Use the Distributive Property to multiply 4 × 14.
Step 1 Draw a rectangle
that is 4 units wide by 14
units long.
Step 2 Count over 10
boxes from the left. Draw a
line to divide the rectangle
into two parts.
The area or the total
number of units in this grid
can be found by multiplying
4 × 14.
Does the rectangle show:
4 × 14
Yes
4 × (10 + 4)
Yes
(4 × 10) + (4 × 4)
Yes
Step 3 Use the
Distributive Property to find
the number of squares in
each of the two sections of
the rectangle. Then add the
partial products.
4 × 14 = (4 × 10) + (4 × 4)
= 40 + 16
= 56
Use the Distributive Property to multiply. Show the partial products
for each and find the sum. Then write a multiplication sentence for
each.
