We have enjoyed all of the Teach Me apps. My son is 4 and has played all of the apps with the content area that is needed. I also used this app when teaching Children with Special Needs. Great for data collection. Only one frustration we have is the letter writing acceptance. I understand the need for correct writing; however, the child has a recognize able letter an the app will rejected it. Maybe levels of acceptance for a beginning writer to a more advance writer of letter and numbers.
