Estimate and Measure with this Great App!
I am mixed about this app, because it is such a different app, compared to other math apps, but it is challenging. It's similar to a game show app where you pick the topic and score points. Also, it might refer to things that kids don't know or can't imagine - the challenging part - so even if you know it and are close, it's hard to hit the bullseye.
It does address estimation and measurement, one of the only math apps that has either.
How I Use It
I would use this in partners. It is a difficult game and I think that talking through the questions would help students out. A few kids on their own would easily fail, but if they had help, then they would do well with this app. It's great for estimating!
