Common Core For Grade 4
Videos, examples, solutions, and lessons to help Grade 4 students learn to apply and
extend previous understandings of multiplication to multiply a
fraction by a whole number.
Understand a fraction a
as a multiple
of 1/b.For example, use a visual fraction model to
represent 5/4 as the product 5 נ(1/4), recording the conclusion
by the equation 5/4 = 5 נ(1/4)
B. Understand a multiple of a/b as a multiple of 1/b, and use this
understanding to multiply a fraction by a whole number. For
example, use a visual fraction model to express 3 נ(2/5) as 6
(1/5), recognizing this product as 6/5. (In general, n נ(a/b) =
C. Solve word problems involving multiplication of a fraction by a
whole number, e.g., by using visual fraction models and equations to
represent the problem. For example, if each person at a
party will eat 3/8 of a pound of roast beef, and there will be 5
people at the party, how many pounds of roast beef will be needed?
Between what two whole numbers does your answer lie?
Common Core: 4.NF.4
Suggested Learning Targets
- I can explain why a/b = a נ1/b using models. For example, 3/4
= 1/4 + 1/4 + 1/4 = (3 נ1/4).
- I can decompose a fraction into multiple unit fractions. 5
7/8 = 5 נ(7 נ1/8) = (5 נ7) נ1/8 = 35 נ1/8 or 35/8.
- I can solve word problems that involve a whole number and a
Using Visual Models and Repeated Addition
Understand a/b as a multiple of 1/b and solve word problems
involving multiplication (4.NF.4a)
In this lesson you will learn how to multiply a fraction by a whole
number by using visual models and repeated addition.

4.NF.4.c - Fraction of a Set Word Problems (Singapore Math)
This video applies multiplying a fraction by a whole number to solve
word problems. He uses the Singapore math modeling strategy of a bar
model and the "unitary method" to illustrate 4.NF.4.c in the grade 4

Multiplying Fractions By Whole Numbers - Pizza by the Fraction
Maria and Luigi decide to open up a pizza shape. For each
pizza they charge $12. It's an additional $3 per topping for each
whole pizza. Pizza are scaled according to the size of each slice.
How much would they charge for each slice in the pizza shown below?
