Grade: Third
Lesson 10 – Use Place Value to Multiply
Week: 11
Learning Targets
Standard: 3.NBT.A.3
Essential Question
How can place value understanding and
properties of operations help solve
multiplication problems?
Big Idea
Understanding the base ten number
system and how numbers can be
manipulated helps develop students'
problem solving skills and number sense. It
also builds an understanding of the
mathematics involved when performing
computations.
Multiply one-digit whole
numbers by multiples of 10 in
the range 10–90 (e.g., 9 × 80, 5
× 60) using strategies based on
place value and properties of
operations.
Vocabulary
basic facts
multiple
multiplication
place value
product
strategy
whole number

This standard extends students’ work in multiplication by having them apply their
understanding of place value. This standard expects that students go beyond tricks that
hinder understanding such as “just adding zeros” and explain and reason about their
products. For example, for the problem 50 x 4, students should think of this as 4 groups
of 5 tens or 20 tens. Twenty tens equals 200.

Journal Task
You add a 3-digit number to 456 in your
head, without using pencil and paper.
What might the 3-digit number be?
What made it easy to do in your head?
Turn over 2 numeral cards (1-9). Add a
zero to the second factor to make a
multiple of 10. Multiply the two factors
and record the product. Repeat 5 times.
