The parents' guide to what's in this app.

Educational Value

Kids can learn how to estimate and compare fractions in various forms including standard, decimal, percent, and pie-chart form. Kids tilt the device to bounce the star so it lands on the correct place on a number line. For example, if the star has the fraction "1/2" written on it, kids bounce the star at the halfway point on the number line. If they get it wrong, they get great feedback. An independent research study also found that kids' learning improves after using the app.

Ease of Play

Many kids will find it easy to tilt their devices to move the star where they want it to go, but younger kids may need a lot of practice to hit the target.

What parents need to know

Parents need to know that Motion Math: Fractions! is an innovative game that teaches kids about fractions. A star has fallen from the sky and has to bounce back into space. Different fractions appear on the star, and kids have to move the star so it bounces on the correct place on a number line at the bottom of the screen. Kids earn stars for completing levels and receive regular praise when they solve problems.

What's it about?

The game structure of MOTION MATH: FRACTIONS! is simple yet effective. Kids can choose from three levels of difficulty, and the games in each level get more challenging as they progress. The game starts with a star that contains fractions written in standard form: numerator over denominator. Kids tilt the device so the star lands on the matching area of the number line below. For example, if the star contains the fraction "2/3," kids have to land the star on the number line so it shows two-thirds. As the game progresses, kids are given different representations of fractions including decimals, percents, and pie charts. Kids earn points and star rewards for correct answers. Multiple players can be entered on a single device, and high scores are tracked.

Is it any good?

Kids often struggle to learn and understand fractions. Motion Math: Fractions! does a great job of presenting the concept in a way that makes it fun and engaging to learn. It's helpful that there are three levels of play, so kids of varying abilities will benefit. It's also nice that fractions are given in different forms and that kids get scaffolded feedback. One downside is the lack of variety with respect to gameplay. Kids may grow tired of the same tilting method required for each game. Adding some other forms of interactivity such as dragging and tapping could help. 

Talk to your kids about ...

  • Families can talk about fractions that are apparent in your daily lives. For example, if kids pour juice into a cup, ask them to estimate how much of the cup is filled. Use different forms such as percents and decimals with older kids. 

  • Have kids sketch a design of their own fraction game. It could be a board game, a computer game, or a card game. Make sure they include some sample problems.
