There are three adding options for this app. The first (top) option is the best for young kids. Although I like that you can "count on" the dots to find the answer, an adult will have to teach a young child how to do this since there is no teaching involved in this app. Also, the other two options for adding are totally inappropriate for young kids since it involves finding the missing addend. These options are best for a second grade student when it is introduced into the school curriculum.
