Motion Math: Zoom



Clever way to learn number line; purchase unlocks full app.

What parents need to know

Educational value
Kids can learn numbers and counting by exploring this interactive number line. The design of Motion Math Zoom helps kids learn how numbers relate to each other, with animals of increasing size corresponding to numbers of greater value; for example, frogs for ones, dogs for tens, and rhinos for hundreds. As kids fill in the number line, they must analyze what they see and decide where each number belongs. Motion Math Zoom makes the abstract idea of number relationships more concrete, giving kids a tangible way to understand essential math concepts.
Ease of play

There are several levels to this game, starting with an intro level, and each level increases the difficulty. Kids can also turn off and on a timer, which is in the form of a needle to pop the bubbles. Instructions are included as kids play, and are also on a help screen.

Parents Need to Know

Parents need to know that Motion Math: Zoom is an educational app that helps kids practice using the number line. Depending on the level, kids can practice with numbers 1 to 1,000, negatives, decimals, and more. However, only six levels are available with the free version of the app; users will need to purchase the full version ($4.99) to access the other 18 levels – and they are reminded to do so frequently.  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.

Families can talk 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?"

Restrictive and boring when it could be so great

Using lines of bugs, frogs, dogs, rhinos and dinosaurs to make the number line come alive is a great idea, and the illustrations are very sweet and work perfectly here, but I was disappointed by the ways in which you can use this app. I was excited about showing my kids an interactive number line to zoom around and just explore on. (Ideally it would go way beyond dinosaurs to the planet- and the galaxy-sized number level.) At least the smaller version of the app, for €2,99, doesn't provide any of this, but instead offers fixed problem sets in which you must move the number line along until the number in the bubble can fill a blank space visible on the screen, then burst the bubble and watch as the number slowly falls into place. There's no indication that the larger version provides an open-ended play option, either, though I haven't spent the additional €2,99 to find out. More gripes: -For each level the sequence of numbers seems to be fixed rather than randomly generated, so the whole thing gets very predictable very quickly. -we can't get into level fifteen at the moment as its first bubble refuses to burst, although the number line under it line is positioned correctly. -To win stars and gain access to more levels, you have to complete the timed version of the lower levels, in which a clicking needle advances toward each bubble, getting ready to pop it and spear the number if you are too slow finding your segment. It's a horrible feeling and you're not given much time, so its difficult although the problems are easy. If the needle reaches the bubble once, you're out and have to start over on the level. For some reason, the number 1 Is repeated ad infinitum at the beginning of each level, at least in the lower levels. I feel I wasted my money on this game, and the worst part is, I really wanted to love it.
