Recommended Ages
99math is generally best suited for roughly 2nd-7th grade, when building fluency with basic operations and fractions is a major focus.

2nd-7th Grades

99math is a game-based platform designed to help kids build math fact and mental-math fluency through short, competitive rounds. Teachers and parents pick a skill-such as addition, multiplication, or fractions-and launch a game that students join from their own devices. Kids race to solve as many problems as they can in a set time, while 99math tracks accuracy and improvement over time. For homeschoolers, 99math can be a powerful supplement for kids who already understand the underlying concepts but need more practice to make facts automatic. It is not a full math curriculum, and the focus on speed may feel stressful for some learners, so we recommend using it in short bursts, with an emphasis on personal growth rather than beating others.

99math is a strong fit for kids who understand the concepts behind operations but need more practice to make facts automatic-and who enjoy a bit of speed and competition. It works especially well in small groups or co-ops where learners can cheer each other on.

Pros

Focused squarely on math fluency; quick to set up and play; engaging for many kids; and provides simple data on accuracy and growth.

Cons

Cons: Emphasizes speed over deep understanding; timed games can be stressful for some learners; requires reliable internet and devices; and works best as a supplement, not a stand-alone math curriculum.

99math is often used in classrooms and may be available through school accounts. Whether families can purchase any premium offerings with ESA, charter, or government funds will depend on local program rules, so it is best to check directly with your provider.

99math provides a free tier with core game functionality. Any premium features or expanded plans are billed through 99math, and pricing may change over time, so we recommend checking the website for current details.

What kids will learn

99math Mission

99math's mission is to help students build confidence and fluency in math by turning repetitive practice into quick, social games that kids are excited to play.

99math Story

Created by a small edtech team in Northern Europe, 99math emerged from the observation that many students were bored or anxious during traditional math drills. The founders set out to design a simple platform that would let teachers and families run live and homework-style math games that feel more like a tournament than a worksheet, while still providing useful data on growth and accuracy.

About Modular Learning

FAQ: Additional Details about 99math

In a typical 99math session, an adult launches a game, learners join with a code, and the screen fills with simple math problems as a timer ticks down. After the round, players see how many questions they attempted, how many they got correct, and whether they improved over time.

To use 99math, an adult creates an account, selects a math skill and level, and starts a game. Students join with a game code on their own devices, answer as many questions as they can during the round, and then see their results. Adults can review basic data to see where more support is needed.

Parents or caregivers choose the skills, launch the games, and help interpret results. Students can generally play independently during a round, but may need reassurance if they are sensitive to time pressure.

Students should already be familiar with the math concepts being practiced and able to read simple numerical expressions on a screen. Adults need a device to host games and a basic understanding of which skills to target.

Adults personalize 99math by choosing which skills to practice, adjusting difficulty, and selecting between live games and homework assignments. They can focus on specific fact families or operations, and track individual student progress to see who needs extra support.

For some kids with ADHD, the bite-sized rounds and immediate feedback in 99math make math practice more engaging than worksheets. For others, the variety and easy access to many games can make it hard to stay focused on a particular skill, so adult guidance and clear goals are important.

99math was not designed specifically for autistic learners, but some may appreciate the predictable rules and short, repeatable rounds of play. Others may find certain visuals, sounds, or time pressures overstimulating, so it helps to preview games and keep sessions short at first.

99math is not a structured intervention for dyscalculia. It can provide extra practice with basic skills once concepts have been explicitly taught elsewhere, but learners with dyscalculia will usually need a dedicated, research-based program in addition.

99math focuses mostly on numbers and visual puzzles, but some games do include written instructions. Younger learners or kids with dyslexia may benefit from an adult reading directions aloud and helping them choose games with minimal text.

99math includes bright colors and simple animations, but intensity varies by game. Families of kids with sensory processing differences may want to stick to calmer titles and lower device volume if needed.

99math is a flexible, informal practice site rather than a therapeutic intervention. It can be paired with many accommodations, such as working in short bursts, playing alongside an adult, or using it only after more structured instruction from another program.

Many gifted learners enjoy the open-ended puzzle and challenge structure in 99math, especially when adults help them seek out more complex games rather than staying with simple drills. It works best as an enrichment tool alongside deeper problem-solving and rich math tasks.

For twice-exceptional learners, 99math can offer a fun way to practice math skills without as much pressure as a formal lesson. Adults can adjust expectations and time limits to fit the learner's energy and focus on a given day.

Profoundly gifted students may quickly outgrow many of the basic games in 99math, but can still enjoy more challenging logic and strategy titles. Treat it as a light supplement and focus main math time on richer, more complex problems.

For some kids with ADHD, the bite-sized rounds and immediate feedback in 99math make math practice more engaging than worksheets. For others, the variety and easy access to many games can make it hard to stay focused on a particular skill, so adult guidance and clear goals are important.

99math focuses mostly on numbers and visual puzzles, but some games do include written instructions. Younger learners or kids with dyslexia may benefit from an adult reading directions aloud and helping them choose games with minimal text.

Because most interaction in 99math involves clicking or tapping rather than writing, it can be easier for kids with dysgraphia than traditional paper drills. It does not, however, address handwriting or written expression directly.

99math offers core functionality for free, with additional features or plans available for purchase. Any paid options are managed directly through 99math, and families should review the latest terms and pricing on the site before subscribing.

Because 99math emphasizes speed, it may be a poor fit for learners who are still building foundational understanding, who experience high anxiety around timed tests, or who process information more slowly and feel discouraged by fast-paced games.

For math fluency practice with a different feel, families might explore Prodigy, Reflex Math, or XtraMath. For deeper conceptual learning, a full curriculum like Beast Academy or Zearn will offer more teaching, with 99math reserved for fluency practice.

99math continues to refine its skill sets, reporting, and gameplay based on teacher feedback, so families may see new features and improvements over time.

Use 99math after concept lessons, not before. Let kids first learn new material in a low-pressure setting, then introduce 99math as a way to reinforce and speed up skills they already understand.

Meet 99math

99math was developed by an Estonia-based team that wanted to make math practice more engaging and social for students around the world. Drawing on experience with classroom tools and game design, they built 99math to support teachers and families in running quick, focused math practice sessions without a lot of prep. A fun fact: 99math gained popularity in part through teacher word-of-mouth and online communities sharing how their classes responded to live math "battles."
