2. INTRODUCTION
This lesson enables students to begin
mastering their multiplication facts.
Students will learn to use patterns and
property theories as strategies for recalling those
facts.
5. INDIANA STATE
STANDARD
3.OA.1: Interpret products
of whole numbers, e.g.,
interpret 5 × 7 as the total
number of objects in 5 groups
of 7 objects each. For example,
describe a context in which a total
number of objects can be expressed
as 5 × 7.
6. OBJECTIVES
Students will:
• Develop computational fluency by
exploring patterns in multiplication for
products involving one-digit factors.
• Understand and use the zero property for
multiplication and the property of one as a
factor in multiplication.
8. MULTIPLICATION
VOCABULARY
Multiple – a number that contains another number an integral
number of times without a remainder
• Example: 12 is a multiple of 3
Factor – one of two or more numbers, algebraic expressions, or
the like, that when multiplied together produce a given product; a
divisor
• Example: 6 and 3 are factors of 18
Product – the result obtained by multiplying two or more
quantities together
Double – twice the amount or multiplied by two
11. HUNDRED CHART

n/Math_4_TTT_9.pdf
• Count by 2s, shading multiples of 2 in yellow. Examine
the numbers carefully.
• Ask:
• What patterns do you notice? (Hint: Are the multiples
of 2 even or odd? What do they always end in?)
• Now count by 5s, circle the multiples of 5 with a blue
marker on your number charts
• Ask:
• What patterns do you notice? (Hint: What do the
multiples of always end in?)
• What do you see when you look at the multiples of 2 & 5?
What do they all end in?
12. HUNDRED CHART CONT.
Now count by 9s. Find a pattern and discuss the
pattern you found with your group.
Find on your chart:
• The multiples that 2 & 9 have in common
• The multiples that 2 & 5 have in common
• The multiples that 5 & 9 have in common
What would happen if you shaded in all the
multiples of 1 on the chart?
13. PROPERTY OF ONE FOR
MULTIPLICATION
The product of a number and 1 is that same
number.
Every number is a multiple of one and itself.
Examples:
8 x 1 = ? 9 x 1 = ? 52 x 1 = ?
1 million x 1 = ?
15. NAME THE DOUBLE
Name the double of : 2(2 x 2 = 4)
For his family reunion Ariel wants to make 2 lemon pies
that use 5 lemons each. How many lemons should he buy?
Then he remembers that his Uncle Bob loves lemons and is
likely to eat 2 pies all by himself. Ariel better make 4 pies! How
many lemons will he need to make 4 pies that require 5 lemons
each?
16. EXPLANATION OF NAME
THE DOUBLE
2 x 5 = 10
4 x 5 = 10 + 10
4 x 5 = 20
• Because 4 is the double of 2, the product of any
number multiplied by 4 will be double the product of
that same number multiplied by 2.
17. NAME OTHER DOUBLES
4 x 2 = 8 and 4 x 6 = 24
• 4 x 6 = 24
• 8 x 6 = 24 + 24
4 x 2 = 8 and 4 x 7 = 28
• 4 x 7 = 28
• 8 x 7 = 28 + 28
4 x 2 = 8 and 4 x 8 = 32
• 4 x 8 = 32
• 8 x 8 = 32 + 32
