exploring multiplication patterns miss key’s third grade math class
TRANSCRIPT
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.
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.
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.
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

HUNDRED CHARThttp://www.teachervision.fen.com/tv/printables/scottfor
esman/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?
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?
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 = ?
ZERO PROPERTY FOR MULTIPLICATION
The product of a number and 0 is 0.
Examples:
3 x 0 = ? 52 x 0 = ? 1
million x 0 = ?
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?
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.
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
