Reflex: Math Fact Fluency
Key Standards Supported
Operations And Algebraic Thinking
|1.OA: Add And Subtract Within 20.|
|1.OA.5||Relate counting to addition and subtraction (e.g., by counting on 2 to add 2).|
|1.OA.6||Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 – 4 = 13 – 3 – 1 = 10 – 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 – 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).|
|Understand And Apply Properties Of Operations And The Relationship Between Addition And Subtraction.|
|1.OA.3||Apply properties of operations as strategies to add and subtract.3 Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.) To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12. (Associative property of addition.)|
|1.OA.4||Understand subtraction as an unknown-addend problem. For example, subtract 10 – 8 by finding the number that makes 10 when added to 8.|
|2.OA: Add And Subtract Within 20.|
|2.OA.2||Fluently add and subtract within 20 using mental strategies.2 By end of Grade 2, know from memory all sums of two one-digit numbers.|
|3.OA: Multiply And Divide Within 100.|
|3.OA.7||Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division (e.g., knowing that 8 × 5 = 40, one knows 40 ÷ 5 = 8) or properties of operations. By the end of Grade 3, know from memory all products of two one-digit numbers.|
|Solve Problems Involving The Four Operations, And Identify And Explain Patterns In Arithmetic.|
|3.OA.9||Identify arithmetic patterns (including patterns in the addition table or multiplication table), and explain them using properties of operations. For example, observe that 4 times a number is always even, and explain why 4 times a number can be decomposed into two equal addends.|
|K.OA: Understand Addition As Putting Together And Adding To, And Under- Stand Subtraction As Taking Apart And Taking From.|
|K.OA.5||Fluently add and subtract within 5.|
Families or individual teachers can purchase access for $35.00 per kid per year. Schools or districts pay $2,995 a year plus $400 for two-hour webinar training.
The Reflex dashboard allows teachers to create classes, add students, and monitor student progress. Teachers can enter each student manually or import a CSV file. Districts can load their class lists in advance so that teachers simply select which students to add to their class. The reports menu allows teachers to track the progress of their entire class and gives details about individual students, including fluency gains and product usage.
ProsKids build math fact fluency through engaging games that hold their attention.
ConsThe program lacks extensions to build on math fact fluency.
Bottom LineReflex is a clever tool to build kids' fluency in all four math operations.

Characters in precarious situations (like falling from a ledge) make kids want to solve problems quickly to reach their goal.
Kids can learn all four math operations accurately and quickly. Games adapt to kids' learning, making the exercises both challenging and within reach.
Available in English and Spanish. Friendly characters walk students through the process and provide feedback.
Reflex: Math Fact Fluency teaches math facts for addition and subtraction for numbers 0-10, and multiplication and division for numbers 0-12. It's best for students who already understand basic math operations and need practice to improve speed and accuracy.
A character named Crabby walks kids through the setup. Kids then answer a set of questions to determine their starting fluency. They can choose from a selection of games appropriate for their level. 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."Read More Read Less
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 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.
Coach Penny’s Picture Puzzle – A practice game in which kids answer math facts to create a puzzle.
Ninja to the Stars – Guide a ninja up platforms by getting the math facts right.
Speed Cube Challenge – An assessment game where kids answer math facts to open a cube.
Reflex is most effective if used regularly for shorter periods of time (15 minutes). Students should end the game wanting more. This will keep kids from getting bored and allow them to become fluent more quickly. Kids can work on Reflex at home or in school. They can track their growth using the Progress Tree, and parents and teachers can view individual reports showing usage and fluency gained. The audio and sound effects could be distracting to others, so be sure students have headphones.Read More Read Less
