What is multiplication?

To multiply means to add equal groups

​Ways to solve multiplication!

There are may ways to solve multiplication we have practiced one way (arrays) and now we will learn 2 other ways​

Modeling Multiplication

I can model multiplication using number lines and set models.

​1 times multiplication

• When you multiply ones the number besides the one is always the answer

• ​For example these are some multiplication problems

• ​1x1=1

• ​1x2=2

• ​1x3=3

• ​1x4=4

• ​1x5=5

​2 times multiplication

• ​2x1=2

• ​2x2=4

• ​2x3=6

• ​2x4=8

• ​2x5=10

• ​2x6=12

• ​2x7=14

• ​2x8=16

• ​2x9=18

• ​2x10=20

​3 times multiplication

• ​3x1=3

• ​3x2=6

• ​3x3=9

• ​3x4=12

• ​3x5=15

• ​3x6=18

• ​3x7=21

• ​3x8=24

• ​3x9=27

• ​3x10=30

​4 times multiplication

• 1x4=4

• ​2x4=8

• ​3x4=12

• ​4x4=16

• ​4x5=20

• ​4x6=24

• ​4x7=28

• ​4x8=32

• ​4x9=36

• ​4x10=40

Are you ready to respond to these questions?

Good work!

Now onto our last digit.

4

Four seems hard but it isnt. You probably think it is hard because it is in a higher level, but it is not.

Ready mate?

Onto the questions!

Hurry! You finished.

:D

Times 5

• When you multiply by five you are adding the same number 5 times

Suppose you are building more robots like this
one. Choose any number of robots to build.
How many wheels do you need?

SPARK YOUR LEARNING

Suppose you had chosen 4 robots to
build. Complete the statement.
If I build 4 robots with ____ wheels
each, I need ____ wheels.

3

3

12

Groups with an equal number of items in each group.

3 groups of 4

3 x 4 = 12

Write a multiplication problem

to match the model:

5 groups of 4

5 x 4 = 20

CONNECT TO VOCABULARY

Times 5

• 5 times 1 is 5

• 5 times 2 is 10

• 5 times 3 is 15

• 5 times 4 is 20

• 5 times 5 is 25

• 6 times 5 is 30

• 7 times 5 is 35

Repeatedly adding together the same number.

4 + 4 + 4 + 4 + 4 = 20

4 added 5 times

4 x 5 = 20

Write a multiplication problem to

match the addition problem:

6 + 6 + 6 + 6 + 6 = 30
