Count On! (Addition)
Counting on is faster
Than counting all you see.
Think of numbers you can add.
Use the count on strategy!
You counted on from 6
And thought 7 and 8.
I clapped the number sentence:
6 + 2 = 8!
I'm starting with the number 5.
Count on. It's up to you.
Tell me what the number is
When the clapping's through.
Ready?
5
[clap]
I'm starting with the number 7.
Count on. It's up to you.
Tell me what the number is
When the clapping's through.
Ready?
7

You counted on from 5
And thought the number 6.
I clapped the number sentence:
5+1 =6!
You counted on from 7
And thought 8, 9 and 10
I clapped the number sentence:
7+3=10!
I'm starting with the number 6.
Count on. It's up to you.
Tell me what the number is
When the clapping's through.

The Turnaround Game (Addition)
It's time to take two numbers,
And add and rearrange.
If you switch the adding order
The answer will not change.
1+2 is 3.
2+1 is 3.
Change around the numbers that you see.
The sum will always equal 3!
Either way you add them,
The answer's still the same
1+2 is 2+1.
Let's all play the Turnaround Game!
2 + 4 is 6.
4 + 2 is 6.
Change around the numbers. Switch and mix.
The sum will always equal 6.
Either way you add them,
The answer's still the same
2 + 4 is 4 + 2.
Let's all play the Turnaround Game!
3 + 5 is 8.
5 + 3 is 8.
Change around the numbers. Calculate.
The sum will always equal 8.
Either way you add them,
The answer's still the same
3 + 5 is 5 + 3.
Let's all play the Turnaround Game!
4 + 6 is 10.
6 + 4 is 10.
Change around the numbers, once again.
The sum will always equal 10.
Either way you add them,
The answer's still the same
4 + 6 is 6 + 4.
Let 's all play the Turnaround Game!
Adding Doubles (Addition)
When we add two numbers
That are the same,
We call it adding doubles
and we play a game!
2 children jump
And jump some more.
2 more join them.
Now there are 4.
Jump while you add.
Jump to the beat.
Jump on the playground,
Not in the street!
3 children jump
And some do tricks.
3 more join them.
Now there are 6.
1 + 1 = 2.
2+2=4
3 + 3 = 6.
Let's add doubles. Add some
more!
4 children jump.
They just can't wait.
4 more join them.
Now there are 8.
4 + 4 = 8.
5 + 5 = 10.
Keep on jumping
While we add again!
1 child jumps.
Her name is Sue.
1 more joins her.
Now there are 2.
5 children jump
And jump again.
5 more join them.
Now there are 10.
Keep on adding doubles
While you jump to the beat.
Jump on the playground
Not in the street!
Count Back! (Subtraction)
When you take a number
And then you subtract,
Use the count back strategy.
It works. That's a fact!
12 - 2 = 10.
We counted back together
We counted back 2.
Start from 8.
And now subtract 1.
Let's count back together
Let's count back one.
7
8 - 1 = 7.
We counted back together
We counted back 1.
When you take a number
And then you subtract,
Use the count back strategy.
It works. That's a fact!
When you take a number
And then you subtract,
Use the count back strategy.
It works. That's a fact!
Start from 12.
And now subtract 2.
Let's count back together
Let's count back 2.
11 10
Start from 20.
And now subtract 3.
Let's count back together
Let's count back three.
19 18 17
20 - 3 = 17.
We counted back together
We counted back 3.
When you take a number
And then you subtract,
Use the count back strategy.
It works! That's a fact!
We Are a Family (Addition/Subtraction)
We are a group of numbers.
We are a family.
We are all related facts.
Watch and you will see.
Each family has three
numbers
To add or to subtract.
These numbers make four
sentences.
It's time to name each fact.
If
1 + 2 is 3.
Then 2 + 1 is 3.
So
3 - 1 is 2,
And 3 - 2 is 1.
These are our related facts
And now our family's done!
We are a group of numbers.
We are a family.
We are all related facts.
Just watch and you will see.
If
4 + 5 is 9.
Then 5 + 4 is 9.
So
9 - 4 is 5,
And 9 - 5 is 4.
These are our related facts
It’s time to learn some more!
We are a group of numbers.
We are a family.
We are all related facts.
Just watch and you will see.
If
4 + 6 is 10.
Then 6 + 4 is 10.
So
10 - 4 is 6,
And 10 - 6 is 4.
These are our related facts
Can you think of more?
We are a group of numbers.
We are a family.
We are all related facts.
Just watch and you will see.
The Commutative Song (Multiplication)
When it's time to multiply
Sing the commutative song.
You can switch around the
numbers
While you sing along.
8 x 6 or
6 x 8.
The answer's still the same.
It's 48!
5 x 7 or
7 x 5.
The answer's still the same.
It's 35!
There's really no denying,
It's very satisfying,
That this rule for multiplying
Is really clarifying!
4 x 6 or
6 x 4.
The answer's still the same.
It's 24!
2 x ll or
11 x 2.
The answer's still the same.
It's 22!
There's really no denying,
It's very satisfying,
That this rule for
multiplying
Is really clarifying!
Three Simple Rules (Multiplication)
There are three very simple rules
That will help you multiply.
They're the 0, 1, and 10 rules.
And they're easy to apply.
0 has a simple rule.
Let me tell you why.
The answer's always 0,
When you multiply.
0x3=0
10 x 0 = 0.
The answer's always 0
When you multiply.
Number 1 has a simple rule.
I know that you'll agree.
Any number multiplied by 1,
Is itself, you see.
4 x 1 = 4.
1 x 9 = 9.
Any number multiplied by 1,
Is itself, you see.
Number 10 has a simple rule,
When you multiply by 10.
All you do is take the number
And put a 0 at the end.
l0 x 5 = 50.
8 x 10 = 80.
All you do is take the number
And put a 0 at the end.
There are three very simple rules
That will help you multiply.
They're the 0, 1, and 10 rules.
And they're easy to apply.
