1. STRATEGIES FOR MULTIPLICATION
COMPLETE NUMBER STRATEGIES
PARTITIONING STRATEGIES
COMPENSATION STRATEGIES
USING MULTIPLES OF 10 AND 100
TWO DIGIT MULTIPLIERS (The area model)

2. COMPLETE NUMBER STRATEGIES
Repeated addition: 73 X 4 = 73
+ 73
292

3. PARTITIONING STRATEGIES
Breaking numbers up in a variety of ways that reflect an understanding of base 10.
27 X X 6
20 X 4 = X 6 = 1200
7 X 4 = X 6 = 360
X 6 =
1608

4. COMPENSATION STRATEGIES
Looking for strategies to manipulate
numbers so the calculations are easier
(more familiar).
Double/Half: X 4
3 X X 4 = 120
(3 X 2) X (18 / 2) X 4 = 12
6 X
