A lot or a little?

The parents' guide to what's in this website.

Educational Value

Reflex builds math fact fluency, which is essential to success in mathematics. Kids gain fluency by learning "fact families," in which they focus on a set of facts for a group of numbers. Subtraction and addition are paired and taught together. Similarly, multiplication and division facts are taught as a family. This strategy helps kids understand inverse operations and reduces the total number of math facts they have to learn. Reflex is a creative and engaging way to build fluency in all four math operations.

Positive Messages

Kids are encouraged to keep trying even when they struggle with a difficult task.

Violence & Scariness

What parents need to know

Parents need to know that Reflex: Math Fact Fluency is a website that helps kids learn math facts by playing games. It teaches addition and subtraction for numbers 0-10 and multiplication and division for numbers 0-12. It's best for kids who already understand basic math operations and need practice to improve speed and accuracy.

What's it about?

A character named Crabby walks kids through the set-up. Kids then answer a set of questions to determine their starting fluency. Each game starts with Coach Penny giving them some rules like "Subtracting a number from itself equals 0." Kids practice that rule, and once they demonstrate understanding, they get to play the game to build their speed. As they progress, they earn tokens to redeem for online "prizes." Kids track their growth using the Progress Tree, and parents can view individual reports showing usage and fluency gained.

Is it any good?

REFLEX: MATH FACT FLUENCY makes practicing and mastering addition, subtraction, multiplication, and division a lot of fun. The program is adaptive, removing the facts kids already know as they play, which keeps them challenged and wards off boredom. For some math rules, kids may "discover" the math rule simply by playing the game. If not, there's always Coach Penny's tutorial to offer help and support. With Reflex's game-based structure, kids are empowered to own their learning.

The idea behind Reflex is that kids need math fact fluency in order to succeed in more advanced math classes like geometry and algebra. The program doesn't take the math any further than the four operations. However, Reflex provides kids with a foundation for all math learning to come.

Talk to your kids about ...

  • Families can talk about ways we use math facts every day. If you eat 3 of your 5 carrots how many do you have left?

  • Families can also discuss reasons it's helpful to learn math facts. Why is practice important in math, music, sports, and other areas?

  • Even though a site is educational, still be aware of how much time kids spend in front of the computer. Check out our advice for setting computer time limits for your kids.
