Roll-Over for Numbers
I'm working on a SCRATCH game, where students are playing a boy/girl who has to walk around town and find equivalent numbers. They're given a fraction, then have to find the equivalent decimal, percent, and simplified fraction.
I want to make it so that there are incorrect numbers out there, and only when they walk over the correct answer, it adds to their score. Any suggestions on how to do this? I thought about the "touching color," but the kids would figure out to match the color, not the number. Thoughts?

Re: Roll-Over for Numbers
Try using the "touching sprite" block so that each fraction is a sprite. Otherwise you can use the x and y position reporters to create a square on your screen that contains the correct answer
<(x position) > [-10] and (x position) < [10] and (y position) > [-10] and (y position) < [10]>
This is should probably be moved to "all about scratch" if you're still unsure :)

Oh, that makes perfect sense! Not sure why I didn't think of the touching sprite. Thanks!
