Question and Answer
Number Family Song
From Discovery Education
A fact family
is when you use three numbers
to put together or take away
No matter if you add or subtract
The same three numbers stay
In a fact family
1+2 is 3
and 2+1 is 3
3-1 is 2
and 3-2 is 1
That's fun!
Here's another!
3+1 is 4
and 1+3 is 4
4-3 is 1
and 4-1 is 3
In a fact family
When you add numbers together
The answer is the same
Doesn't matter which is first
They turn around just the same
In a fact family
2+3 is 5
and 3+2 is 5
4+2 is 6
and 2+4 is 6
Here is more
8+1 is 9
and 1+8 is 9
6+4 is 10
and 4+6 is 10
In a fact family
When you take the numbers in the family to add or subtract
5+3 is 8 and 8-5 is 3
Now that's a related fact
In a fact family
5+1 is 6
and 6-1 is 5
6+2 is 8
and 8-2 is 6
Some more related facts
9+1 is 10
and 10-9 is 1
3+6 is 9
and 9-6 is 3
