Math Fact Resources
What are Math Facts?
Math facts are defined as addition of single digit numbers (1+2, 4+3, 7+9 etc..), subtraction of corresponding addition sums (18-7, 2-1, 12-3), multiplication up to 10, and corresponding division of those products.
Math fact fluency is considered a building block to higher level math. Efficient and accurate recall of math facts builds confidence and frees up working memory for more complex math problem solving.
The goal of math fact fluency is not teaching students to just memorize math facts but to build number-sense based strategies to determine math facts and with practice – to help build efficiency, flexibility and accuracy with math facts.
Use the unknown addend model for subtraction - if your equation is 12-9 use what you know about addition to solve "what plus 9 = 12? It's 3!"
This can be expanded into much greater number equations like 63-44 = Build up from 44 to get to 63 to solve 44+6=50 and 50+13=63 so the difference is 13+6=19
Grade Level Expectations
Rising 1st Grader – Identify numbers 0-30 and build number combinations 0-10 using manipulatives
Rising 2nd Grader – Automatic recall of addition facts up to 9+9
Rising 3rd Grader – Automatic recall of addition & subtraction facts up to 20
Rising 4th Grader – Automatic recall of multiplication fact families through 10 and corresponding division facts
Rising 5th Grader – Automatic recall of all multiplication facts up to 12 and corresponding division facts
Use what we know about fact families to help remember division facts. Use what you know about multiplication to solve division facts. 45/9 is 5 because I know that 9 groups of 5 is 45
You can also use what you already know about your x2, x4 and x8 facts for division facts with those divisors. For example, if 2x6 is 6 doubled (12), then 12/2 must be12 halved which is 6. To extend this strategy, if you are dividing by 8, take the dividend and half, half, half it - for example 64/8 = 64 halved is 32, 32 halved is 16 and 16 halved is 8.
