What
exactly is math fact fluency? It isn't
about speed as many people beleve.
NCTM President Linda M. Goja summed it up this way in a 2012
article, Fluency: Simply Fast and Accurate? I Think Not!
"Focusing
on efficiency rather than speed means valuing students’ ability to use
strategic thinking to carry out a computation without being hindered by many
unnecessary or confusing steps in the solution process. Accuracy extends beyond
just getting the correct answer. It involves considering the meaning of an
operation, recording work carefully, and asking oneself whether the solution is
reasonable."
Your
weekly math routine should include strategy lessons as well as time to practice
basic facts. If you choose to use timed
drills, the time should be long enough for students to apply the strategies
they're learning. (And I don't consider counting on your fingers as a
strategy!) With practice, the facts will
become more automatic as students apply the strategies more quickly.
Here
are some strategies that worked well in my classroom:
1.
Zero rule, 3 + 0 = 3 / 5 - 0 = 5 and 6 X
0 = 0 / 8 ÷ 0 = 0
2.
Counting up or backwards, works well when adding or subtracting by 1 or 2
3.
Ones' rule for multiplication and division, 6 X 1 = 6 / 9 ÷ 1 = 9
4. Fact Families, works well because students
learn the relationship between addition/subtraction and
multiplication/division.
5.
Doubles, kids love to memorize these facts.
9 X 9 = 81 is always their favorite!
6. Nines,
since nine is just one away from 10 there are some nifty tricks to add,
subtract, multiply and divide by 9.
7.
Numbers with zero in the ones place.
Kids should quickly see that 7 + 10 = 17 and 14 - 10 = 4.
I
know there are many more fact strategies and you probably have a few of your
own favorites. I'd love to hear what
works in your class. Please share your favorite strategies in the comments section below.
Games
are a great way to get kids to practice the facts. This game, Catch Me if You Can, is super fun
and can be used with any skill practice.
Students answer questions and then move around the board trying to "catch" the other player. Click on the pictures to download your free copy.
