What parents need to know
Parents need to know that Motion Math: Zoom is an educational game that helps kids practice using the number line. It is currently only available through the Motion Math app, which combines six games into a single app that requires a subscription service to play ($2.99 monthly, or $29.99 annually). Depending on the level, kids can practice with numbers 1 to 1,000, negatives, decimals, and more. Users can share high scores via the Game Center social network, but participation is optional.

What's it about?
In Motion Math: Zoom, kids physically interact with the number line by swiping with one finger to move it around and pinching with two fingers to zoom in and out. Numbers appear in bubbles above the number line, and kids swipe and zoom to find the empty space where the number fits on the line. When kids find the right spot, they tap to pop the bubble, and the number floats into place.
Is it any good?
MOTION MATH: ZOOM is a fun and creative way to practice using the number line and to put different kinds of numbers in order. Kids physically interact with the number line, moving it around, zooming in and out, until they truly understand how it works. The graphics and the game are fun, and the included creatures are very useful in demonstrating scale. Although the app teaches how to use the number line very well, the constant reminders to purchase the full version of the app detract from the fun.
Talk to your kids about ...
Help kids create their own number lines; hang up a string then use clothespins or paper clips to attach numbers to the line.
Ask kids "Which is bigger?" questions to help them practice visualizing numbers on the number line. Tailor your questions to your child's learning level, for example, "Which is bigger, ½ or ¼?"
