How I Use It
I have used this on an ipad with and Apple TV, and with a smart board, as a whole class review. The students love the little fish and movement, and the Hippo's encouragement is a definite hit with the younger students.
As an individual and small group center set, the students encourage one another, and work hard to increase their scores.
As with any product of this nature, while more engaging than simple flash card review, I would limit the time spent on this to no more than 30 minutes.
For older students (i.e., middle school student who need an extra boost), I would use this as an individual station, NOT as a whole or small group, simply due to the more elementary format.
I have had my own children use this at home, and they are far more engaged for a longer period of time than with simple flash card sets.
