Once your child is able to spell 3 letter words (please see phonics - "ABC and Words" app for 3 letter words), it is time to take the next step and move on to 4 letter words.
This app provides 100+ common 4 letter words. It would be a natural and gradual progression from 3 letter words.
The app provides the same fun interface as the phonics app (which has been featured by apple and has been a tremendous success).
Features:
1) It is FUN
2) How do you know for sure whether you child really knows the spelling or is he/she making an intelligent guess based on the four letter choices provided?
- Just turn on all the 26 letters.
3) Did we mention: "It is FUN"
An actual demonstration is worth more than a 1000 words. Please check out the the free version to see it for yourself.
