How Math Expanse Works
Created by experienced educators, Math Expanse uses a game-based environment to teach mathematical concepts through solving problems. The game combines independent asynchronous play and online teaching sessions where math experts share feedback and answer math questions.
Solve Problems
Twice a week players receive a set of math problems that help them learn new concepts and build new skills. Solving problems allows players to obtain information needed to advance in the game.
Discuss Solutions
Once a month players meet with our math experts to receive feedback on solutions they have submitted. Discussions allow for a deeper understanding of the topic. Small groups give everyone a chance to participate.
Unlock Maps
By solving problems gamers advance to the next level. They can choose to join an alliance in order to improve their chances. Online chat allows them to communicate and seek help when needed.
Win the Title
The game has an objective and a scoring system. Players increase their score by earning rewards along the way. Five players with the highest score receive the title of the Ultimate Math Champion.
Math Topics
Math Expanse draws from four content areas: arithmetic and number theory, logic and reasoning, combinatorics, and geometry. Additional topics may be introduced during the game depending on the player's progress.

Why Choose Math Expanse

Game-based Learning for Kids Aged 10 -13

Our game has been crafted by middle school teachers with middle-schoolers in mind. The gameplay structure motivates students to explore math concepts by doing rather than observing. Problems are adjusted by level of difficulty to make sure that both ambitious and reluctant learners are challenged at the level that's right for them.
Improves Skills and Deepens Understanding
By introducing challenging exercises we help students apply fundamentals to problems they have not encountered before. Rather than memorize formulas players learn to discover solutions and integrate different areas of knowledge in order to understand how math works.
Increases Confidence and Ability to Learn Independently
Players practice at their own pace, tackling problems independently and asking for support when needed. The game motivates them to rely on their natural curiosity and explore solutions without the threat of a test. They can practice crucial skills in a stress-free environment.

This game has a great selection of engaging math problems that gradually increase in their difficulty. I never knew that math could be taught this way, by solving problems rather than learning theory. My daughter Esti is far from being a math geek, but she really enjoyed this game and is looking forward to this year's tournament.

Esti's school doesn't teach math at this level. I feel like she now can apply to a college prep program right away. In fact, this game does teach some college-level stuff like combinatorics and graph theory.
I wholeheartedly recommend this program to kids who want to learn more about math in a fun and stress-free way.

Our family has been moving a lot for the past two years and this online game helped my son to stay motivated and focused on his math studies.

The game is rooted in a strong mathematical tradition of problem-solving. It draws the best from the European school of math that challenges kids to use math skills at a whole different level.

My son now applies problem-solving skills not only in math but also in his science classes. Thank you for making this possible!
About Math Expanse
What is the recommended age for Math Expanse?
The game is designed for players aged 10-13. While individual levels of knowledge vary, in our experience younger children have difficulty solving problems at this level. Many 14-year-old children might find this game interesting, but the more experienced older players might feel that the game is not challenging enough. We suggest that your child tries this game for 30 days and if they don't enjoy it you can cancel your subscription free of charge.
Does Math Expanse support what my child is learning in school?
The game includes challenging and engaging problems that are not limited to the school curriculum. Learning to solve these problems will likely help your child approach school math with greater confidence and apply problem-solving skills in a variety of classes.
What kind of methodology does Math Expanse use?
The game draws from a problem-solving approach to math education developed in countries with strong mathematical traditions, for example, East-European countries, Singapore and India. This approach is centered on the knowledge that kids are adaptable and curious learners. Activating their natural thinking patterns by encouraging them to seek solutions is seen as a much more beneficial learning strategy than the generally accepted approach of memorizing and learning to apply math formulas.
What is the Math Expanse storyline?
The game is set in the future where people have to battle Artificial Intelligence for control of the planet's resources. By solving math problems players unlock new maps and take control of the game 'servers' thus preventing the A.I. from establishing dominance. 
How much time does the game require?
The Math Expanse game runs for 8 months and players are given assignments twice a week. They are expected to complete the week's assignments by Saturday, but results will be accepted at later dates as well. Different players complete the game tasks at different paces, but generally, students require 2-3 hours a week to complete the tasks. Once a month players meet with math experts for a 45 - 60 minute study session. New players can join the game at any given time.
My child is an experienced gamer, will they benefit from this game?
Many games like Minecraft might help players develop an understanding of spatial relationships or faster reflexes. Although engaging, these games aren’t designed to be educational. Our game was made to achieve learning outcomes. Math Expanse allows players actively take charge of their learning, as opposed to watching a tutorial or reading a textbook. Children who like gaming will likely benefit from a game-based approach.
My child dislikes math, will they enjoy this game?
The game is designed with different types of learners in mind. Children who are reluctant learners or perceive math as difficult will benefit from a low-pressure environment where non-standard problems require creative solutions.   
My child is struggling with solving problems, should I help?
The game encourages independent learning. If the player has difficulty solving problems they should look for clues inside the game. It is best that parents refrain from trying to find solutions themselves. If you feel that the child can not keep up with the game you can write to us via the game chat or Subscription Support form.
Can my child play with their friends?
Math Expanse is a great game to play with friends. Players can communicate with other players via the game chat. They can form alliances and work together to unlock new maps.
