Fill in the blank for the following expression.
2 x 6
____ rows of ____
2 x 8 = m
What does the variable m equal?
m = 16
5 x 4 = 2 x ____
5 x 4 = 20
2 x 10 = 20
so 5 x 4 = 2 x 10
Solve for the missing variable x.
x = 30
What is the product in the following equation?
8 x 2 = 16
The product is 16.
Draw the array for the following expression.
5 x 2
3 x s = 21
What does the variable s equal?
s = 7
3 x ____ = 9 x 2
9 x 2 = 18
so 3 x __ = 18
3 x 6 = 18
Make a ratio table for the following equations.
2 x 4 = 8
3 x 4 = 12
4 x 4 = 16
Give me two equations that would represent the commutative property of multiplication.
Draw the array for 5 rows of 6.
4 x R = 32
What does the variable R equal?R = 8
True or False
6 x 4 = (6 x 2) + (6 x 2)
True!
What is the missing information?
11
Using a doubles plus one fact, how would I solve for
3 x 6
so 12 plus one group of 6 equals 18
How many rows are in the equation 4 x 3?
4 rows with 3 in each row.
What is 4 x 9?
4 x 9 = 36
What does 6 x 8 equal?
I know that 5 x 8 equals 40, so one more group of 8 is 48.
6 x 8 = 48
What does x equal? Use facts given to help solve for the variable.
x = 8
9 x 7 = 63
63 - 7 = 56
(5 x 2) + (5 x 2)
5 x 4
What equation matches this array?
12 x 4 = M
12 can be broken up into 10 and 2.
10 x 4 = 40 and 2 x 4 = 8
40 + 8 = 48
What is 8 x 8?
8 x 8 = 64
What is the missing information?
18 = 6 x 3
24 = 6 x 4
42 = 6 x 7
Explain commutative property of multiplication and give an example of an equation...
For example: 4 x 5 = 20 and 5 x 4 = 20
