![]() Right now, you might be thinking, “Ok great. This is crucial for kids to get before they move on to more complex mathematics. This is important for kids to understand as they begin to work on addition and subtraction word problems.įinally, fact families help show the relationship between addition and subtraction. Likewise, when you take the whole group and remove one of the parts, you’re left with the other part. That when you have two parts and you put them together, you get the whole group. They can also see the part-part-whole model of addition and subtraction. In other words, they can see that when you switch the addends, the answer is still the same. Seeing the relationships within a fact family helps kids to see mathematical properties, such as the commutative property, that a + b = b + a. In this case, it would be 3 + 3 = 6 and 6 – 3 = 3. When you have two numbers that are the same in a fact family (in other words, the two “parts” are the same) such as 3, 3 and 6, you will have exactly 2 equations, 1 addition and 1 subtraction. When you have 3 different numbers, there will be exactly 4 equations, 2 addition and 2 subtraction (as seen above). Read our full disclosure here.* What Are Fact Families?Īn addition and subtraction fact family is a set of three numbers that form a group of addition and subtraction facts.įor example, the numbers 2, 3 and 5 form a fact family, because they can be used to write the following equations: *Please Note: This post contains affiliate links which help support the work of this site.
