Developed at the Stanford School of Education, Motion Math HD follows a star that has fallen from space, and must bound back up, up, up to its home in the stars. Moving fractions to their correct place on the number line is the only way to return. By playing Motion Math, learners improve their ability to perceive and estimate fractions in multiple forms.

“All I can say is, WOW!…Our 3rd grader said he “wished he could do this for math every day.” Our 5th grader agreed.” - Ashley Allain, HyperHomeSchool

“My 7-year-old daughter played Motion Math totally absorbed for five minutes and then came back, very focused on moving faster through the game. The day before school started, I asked her what she wanted to learn and she said “Fractions! Because they are fun.” Thank you, Motion Math!” – Leigh Anne Gilbert

“Dude, that’s a good game! There’s a lot of variety in the’s so addicting.” – Kyle, 14

“ move your way toward a better understanding of numerical relationships, one bounce at a time. 4.5 stars.” – Warren Buckleitner, Children’s Technology Review

"Motion Math provides a much-needed experience to bring the body more fully into mathematics learning." – Roy Pea, David Jacks Professor of Learning Sciences, Stanford University

Loved by children as young as 7 and as old at 17 (and adults too!), Motion Math gives learners a physical experience of the number line and an intuitive feeling for fractions. Fractions are a notoriously difficult area and if a learner never gains a gut sense for them, it can impede progress in more advanced forms of math. One reason fractions are tough is that they can be written in so many different ways! Motion Math helps learners perceive and estimate many representations -- numerator over denominator (1/2), percents (50%), decimals (.5), and even pie charts.

Motion Math was inspired by embodied cognition, research suggesting that connecting one's body to abstract concepts can deepen understanding. By estimating each problem with its distance on the number line, learners can develop a fast, accurate perception of fractions.

The Motion Math game follows a star trying to return to its home in a far-away galaxy. Moving up through different levels motivates a player to keep playing and keep learning, while bonus levels practice an important variation on the number line theme - is one fraction more or less than another? Progress stars, sound and star effects, and exclamations (“Yes!” “Perfect!”) reward a player for solving problems.

If a player is having trouble, increasingly helpful hints (what educators call "scaffolding”) guide him or her to the correct place on the number line.
- First, a directional arrow is shown.
- Next, tick marks show the fraction’s denominator.
- Third, similar fractions are shown for comparison.
- Lastly, in early levels, a vertical arrow shows exactly where to go.

- Intro level shows player how to tilt to control the star.
- Later levels practice improper fractions and negative decimals.
- Beginner, medium, and expert modes for different learners.

My 6 5/6 year old girl really enjoys this and has been getting better at understanding fractions. One complaint is that I can't figure out how to get to the main menu on launch. It always runs through the demo and game first.

Very enjoyable, user friendly, and educational to boot!

This app is...quite good!


I learned to play this game on iPads at school and I loved it and got it for my sister and I. Ignore the negative reviews. SWEET!!! :)
