The fact family of 0, 0, and 4 would include the addition and subtraction equations: 0 + 0 = 0, 0 + 4 = 4, and the subtraction equation: 4 - 0 = 4.
The fact family of 3 and 9 3+9 9+3 9-3 3-9
1 & 3
write three numbers that makes a fact family
The operation, division, is not symmetric. There is a number, x, such that x*3 = 0. In fact x is also 0. But there is no number, y, such that y*0 = 3.
the fact family is 3 because 3 goes into all of them
The fact family of 0, 0, and 4 would include the addition and subtraction equations: 0 + 0 = 0, 0 + 4 = 4, and the subtraction equation: 4 - 0 = 4.

Fact families are 3 numbers that are related, just as the people in a family are related. They make a set of related math facts.
A fact family is when the same 3 numbers are used in addition and subtraction sentences. An example would be 3+4=7, 4+3=7, 7-4=3 and 7-3=4
The fact family of 3, 9, and 27 involves multiplication and division relationships. In this case, the numbers 3, 9, and 27 are related as follows: 3 x 9 = 27, 9 x 3 = 27, 27 ÷ 9 = 3, and 27 ÷ 3 = 9. These equations demonstrate the fact family connections between the numbers 3, 9, and 27 through multiplication and division operations.
Fact family in first grade math is using 3 numbers and using the operations: Addition and Subtraction.
