Are fact families for even and odd numbers?
Yes.
Yes, fact families can be applied to both even and odd numbers. A fact family is a group of math facts that share the same numbers, but to create different equations. In the case of even and odd numbers, we can still create fact families.
To understand fact families for even and odd numbers, let's start with what even and odd numbers are. Even numbers are divisible by 2, while odd numbers are not. For example, 2, 4, 6, 8 are even numbers, while 1, 3, 5, 7 are odd numbers.
Now, let's create a fact family using an even number, such as 6. The fact family for 6 would include the following equations:
6 + 0 = 6
0 + 6 = 6
6 - 0 = 6
6 = 6 - 0
In this fact family, we use 6 as the main number and create equations by adding or subtracting other numbers (including 0) to equal 6.
Similarly, we can create a fact family using an odd number, such as 5. The fact family for 5 would include the following equations:
5 + 0 = 5
0 + 5 = 5
5 - 0 = 5
5 = 5 - 0
Again, we use 5 as the main number and create equations by adding or subtracting other numbers (including 0) to equal 5.
So, in conclusion, fact families can be applied to both even and odd numbers by using additive and subtractive operations with the given number and other numbers to create related equations.
