What's It About?
In REFLEX: MATH FACT FLUENCY, a character named Crabby walks kids through the setup. 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?
This program makes practicing and mastering addition, subtraction, multiplication, and division a lot of fun. Reflex: Math Fact Fluency 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 rule simply by playing the game. If not, there's always Coach Penny's tutorial to offer help and support. 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 basic operations. But Reflex provides kids with a foundation for all math learning to come.
Talk to Your Kids About ...
Families playing Reflex can talk about ways we use math facts every day. If you eat three of your five carrots, how many do you have left?
Families can also discuss why it's helpful to learn math facts. Why is practice important in math, music, sports, and other areas?
Though its focus is on learning math facts, consider how the design of the site makes kids feel. Does their avatar feel like them? What about their classmates? What could the design add to make their avatar look more like them?
