There are a few minor considerations and issues when thinking about buying the Nesy programs. For some students, their reading and vocabulary may not be at a level which matches their keyboarding and mouse skills. For example, my daughter (age 6) found she enjoyed the fishing game on Nessy Gamesplayer and could easily manage the actual learning task, but struggled to use the mouse efficiently enough to compelte the game before getting frustrated with it.
There are differences in level for the various reading activities and games, so that it may not be appropriate for the same student to do all the games.
As with most education software, it is important to keep your eye on the main task and not allow students (and yourself) to indulge in the temptation of 'busy time'. Reading and education software based activities should be based on a clearly expressed goal for elementary student learning, and should be used to provide practise of skills, motivation of learners, and activities.
Nessy does all of the above well!
