10Multiply Mixed Numbers Unit
Objective: Learn how to multiply fractions and mixed numbers. This activity will test students’ ability to use
the multiplication skills from the previous
Make multiplication sentences using mixed numbers and whole page. Explain to students the concept of
numbers. The products must be whole numbers. multiplication sentences.
Have students use the given numbers and number sentence structures to create multiplication
sentences that have whole numbers as products.
Have students use the given numbers and
number sentence structures to make
multiplication sentences that have whole
_\ _\ numbers as products. Mention to students
that some problems may have more than
3 1 4 = (3 4) ( 1 4) 3 1 8 = (3 8) + ( 1 8) one correct solutions.
2 2 4 4
Example:
= 12 2 = 24 2
Make a multiplication sentence from the
= 14 = 26
numbers 2, 3, 6 and 9.
Product: 14 Product: 26 9 2 6 (9 6) ( 2 6)

6 2 9 = (6 9) + ( 2 9) 1 2 10 = (1 10) ( 2 10)

= 54 6 = 10 4
= 60 = 14
Product: 60 Product: 14
9 2 6 = 58, 3 2 9 = 30 5 1 10 = 55

10. Multiply Mixed Numbers 89
When beginning the multiplication process of these problems, some students may have difficulty structuring
the dual multipliers and put numbers in the wrong place to produce an incorrect result.
Example: 3 1 4

3 1 4 (3 4) (3 1 )
2 2
12 1 1

13 1 Incorrect

Making and checking a complete multiplication sentence is a good method to eliminate such mistakes.
