Fact Family Village is a map of the families of facts that add up to the numbers from 0-10. Streets are named with the ordinal numbers. On each street you will find all of the combinations which add up to that sum. Click the streets to see a closer view, then click the houses to see the number sentences in that family of facts. Don't forget to close the houses after you look inside.
Here are some important definitions from Everyday Math Click the kids to hear them read aloud
Fact Family: A set of related arithmetic facts
linking two inverse operations. For example,
5+6=11, 6+5=11, 11-5=6, and 11-6=5
are an addition/ subtraction fact family. Similarly,
5x7=35, 7x5=35, 35÷7=5, and 35÷5=7
are a multiplication/ division fact family. Same as
number family.
Sum: The result of adding two or more numbers.
For example, in 5+3=8, the sum is 8. Same
as total.
Difference: The result of subtracting one number
from another. For example, the difference of
12 and 5 is 12-5=7.
Commutative Property of Addition: A property of
addition that two numbers can be added in either
order without changing the sum. For example,
5+10=10+5. In Everyday Mathematics,
this is called a turn-around fact, and the two
Commutative Properties are called turn-around
rules. In symbols:
For any numbers a and b, a+b=b+a.
Subtraction is not commutative. For example,
8-5≠5-8 because 3≠-3.
