CMath Vo abulary Identity Property of Multiplication: the product of 1 and any number equals that number

Zero Property of Multiplication: the product of zero and any number equals 0

3. Have students use what they have learned 3 . Find the missing numbers.
previously to find the missing numbers in the
multiplication sentences. a. 8 4 b. 3 5 c. 7 1
5
4. Have students understand that the result 3 3
on the left is the same as the result on the 175
right of the equal sign before solving the 252 213
problems.
4 . Find the missing factor. b. 6 7 = 42
After, explain about Identity Property of
Multiplication and Zero Property of a. 8 3 = 24
Multiplication.
c. 4 6 = 8 3 d. 7 4 = 25 + 3

e. 24 1 = 24 f. 16 0 = 0

g . 17 1 = 17 h. 0 23 = 0

Identity Property of Zero Property of
Multiplication Multiplication
The product of 1 and any
number equals that number. The product of zero and
any number equals 0.
4 1=4
5 0=0

Properties of Multiplications
Students can use the properties of multiplication, which they have learned so far, and apply them when
doing multiplication (all levels). Have them use the Identity Property of Multiplication and Zero Property of
Multiplication. This will help them calculate big numbers.
Example: 54,681 1 54,681, 46,414 0 0.
