I am not one to buy paid apps. I'm a cheap-o that way. But when my son was having trouble learning to count above ten, my friend who is a first-grade teacher told me about this app. Her daughter is about 7 months younger than my son and was counting to 30. She said it was nothing she was teaching her, she learned from the app! I had to buy it. Sure enough, within a week, my son was counting to 30. It actually will help your child learn how to count to 100! There is also a catchy tune, but fair warning, it will get stuck in your head! Each number has a different counting game attached to it. TallyTots Counting is only $2.99 and well worth every penny.
