What is the make a 10 strategy?
In 1st grade, as students begin learning their basic addition facts, they apply that knowledge in a strategy known as make a ten to help make sense of facts that might otherwise be hard to memorize, such as 8 + 4 or 9 + 5. To use the strategy, students decompose one of the addends to make a ten from the other.

What are number facts to 20?
Knowing addition and subtraction facts (or number facts) to 20 by heart means being able to quickly know the pairs of numbers which make a total of twenty, as well as the associated subtraction facts. For example, if you know that 13 + 7 = 20, then you should also recognise that 20 – 13 = 7 or 20 – 7 = 13.
How do you write a subtraction fact?
For example, you can form a fact family using the three numbers 3, 10, and 13: 10 + 3 = 13, 3 + 10 = 13, 13 − 10 = 3, and 13 − 3 = 10. Subtraction facts − Here the difference of two of the three given numbers is the remaining third number.
What are examples of count on facts?
Counting on means that you start with the biggest number and then count up from there. For example, to add 5+3, start with the “5” and then count up, “6, 7, 8.” This is to discourage students from counting like this: “1, 2, 3, 4, 5…..
What are basic math facts?
Basic math facts are defined as computations involving the four basic math operations: addition, subtraction, multiplication, and division; using the single-digit numbers, 0 – 9. These basic facts are often referred to in. current literature as “basic number combinations”.
What is the fact family for 15?
15 – 10 = 5 and 15 – 5 = 10. These are the two subtraction sentences for this fact family. Four different number sentences all using the same three numbers; that’s a fact family!
What is the fact family for 2/4 and 6?
For example, the addition/subtraction fact family for the numbers 2, 4, and 6 consists of the following: 2 + 4 = 6, 4 + 2 = 6 and 6 – 4 = 2, 6 – 2 = 4. Fact families involving doubles facts consist of only two facts.
What is the fact family for 6 9 15?
Similarly, 15- 6= 9 (‘9’ is also the member of the given family). Hence 6, 9 and 15 form a fact family since they form equations among themselves!
What is the fact family of 3/9 and 12?
Also, addition and subtraction are inverse operations, so our fact family also includes 12-3=9 and 12-9=3. So, we have a fact family that includes the facts 3+9=12, 9+3=12, 12-3=9 and 12-9=3.
What is the fact family of 12?
A fact family is a group of math facts using the same numbers. In the case of addition/subtraction, you use three numbers and get four facts. For example, you can form a fact family using the three numbers 10, 2, and 12: 10 + 2 = 12, 2 + 10 = 12, 12 − 10 = 2, and 12 − 2 = 10.
What is the fact family of 3?
Fact families are 3 numbers that make up a set of related math facts. An example of a fact family for multiplication and division is 2, 3, and 6: 2 X 3 = 6, 3 X 2 = 6, 6 2 = 3, and 6 3 = 2. ChartWorld is an excellent tool for showing fact families. Start with a 6-column chart and click on the number 2.
What is a fact family in 2nd grade math?
In math, a fact family can be defined as a group of math facts or equations created using the same set of numbers. The fact family shows the relationships between the three numbers involved. In an addition and subtraction fact family, there are four addition and subtraction sentences created using three numbers.
What are math facts 2nd grade?
Math Facts: Addition and Subtraction Addition and Subtraction Math Facts should be mastered by the end of the 2nd Grade. Students will review Math Fact Addition strategies such as “Doubles” (6+6 or 4+4), “Turnarounds” (2+7 = 7+2), “Near Doubles”, “Almost Doubles” or “Doubles Plus 1” (6+6+12, so 6+7= one more, or 13).
What is the fact family for multiplication?
Fact family: It is a set of four related multiplication and division facts that use the same three numbers. For example: The fact family for 3, 8 and 24 is a set of four multiplication and division facts.
