My Take
Our overall opinion of this is a great teaching tool as long as the students are using it in the correct way, we have a few little ones that will just play the same game over and over again and get several lessons completed, however they are only memorizing how to do this one game instead of learning how to master the skills in all areas. As for the older ones, they get frustrated easily because they feel there is not enough instructions on how to complete it. Overall, we think it is a great teaching tool and it has been a huge success in our school.
How I Use It
We use this daily in addition to offline teacher led instruction. We love it because we can use it to reinforce what we are teaching in class.
