When you add you put together
When you add you get the sum
It's taking 2 or more numbers
And getting a greater one
Adding is called addition
When you subtract you take away
When you subtract you get the difference
It's taking one number from another and always getting less
Subtracting is called subtraction
Let's try an adding problem I think you can solve
If you have 3 pencils 3
And you add 2 more pencils 2
How many pencils do you have all together?
1, 2, 3, 4, 5
3 + 2 = 5
Let's try another adding problem, I think you can do it
If you have 2 dogs 2
And you add 2 more dogs 2
How many dogs do you have all together ?
1, 2, 3, 4
2 + 2= 4
Let's try a subtracting problem
I think you can solve
If you have 4 balls 4
And you subtract 2 balls 2
How many balls do you have left?
1, 2
4 - 2 = 2
Let's try another subtracting problem
Think, you can do it
If you have 6 apples 6
And you subtract 3 apples 3
How many apples do you have left?
1, 2, 3
6 - 3 = 3
Now listen to this cool rule about number 0
When you add or subtract 0 the number doesn't change
When you add or subtract 0 the number stays the same
When you add you put together
When you add you get the sum
It's taking 2 or more numbers
And getting a greater one
Adding is called addition
When you subtract you take away
When you subtract you get the difference
It's taking one number from another and always getting less
