Find each product by factoring the tens. Draw rectangles
if you need to.
11. 3 × 2, 3 × 20, and 3 × 200 12. 7 × 3, 7 × 30, and 7 × 300
6; 6 × 10 = 60;
21; 21 × 10 = 210;
6 × 100 = 600
21 × 100 = 2,100
13. Stretch Your Thinking Write a word problem that
could be solved using the rectangle model shown.
Then solve the problem by finding the tens product,
the ones product, and the total product.

Word problems that could be solved with $35 × 4
will vary. Tens product: $30 × 4 = $120. Ones product:
$5 × 4 = $20. Total product: $120 + $20 = $140.
