Ratings and Reviews


Reading Buddies

This is a wonderful app for developing thinking skills and problem solving. It is unique in that you can choose the type of problem with unknown numbers in all positions. It is easy enough that students can learn HOW to solve word problems. There are two types of counters available to model the program. My one wish would be to be able to write also. It would be wonderful to be able to annotate, draw and write while solving the problems.

Fix the voice!!


I bought this app for my classroom, but my first graders need help reading the problems. I was happy to read that there was a read aloud option, but the voice is so automated that I don't think they would be able to understand what is being said! Very disappointed!

Fix it please!!!

This would be a fabulous app, but I seem to having the same problem with all the apps by this company and the last reviewer...... The screen goes black. I really love this app...... Please fix the problem!! I am a kindergarten teacher and I would love for my school to purchase all the apps to support the common core standards!!!
