Summary: I had this for the PSP for my older son. My 6 year old now plays it on his DS. It's great to say, sure you can play your DS, as long as its Spelling Challenge ... It has really improved his reading ability.
Summary: I got this for my first grader and it's just to hard. It's not helpful for those just learning because 1) It doesn't say the word. No audible to go with the visual. 2) No matter what age you input, it starts you at a 2nd or even 3rd grade level. Yet it offers age 1. Stupid.
Summary: My son is in the first grade, reads at third grade level, but is just learning to spell. Even the lowest levels are a little hard for him right now. We are going to to a different one (Scripps).
