My kids love this

Matthew Maloney

Great app for kids who like things set to music. My 5 and 3 year old love these apps! My only wish is that in the counting it would go to 100 to meet the Kindergarten standards at our school. My kids know how to skip count by 2, 5, 10 and this reinforces those skills and builds on multiplication skills without them knowing. I'll rate it a five when they add skip counting to 100!

Should have all numbers in one app


My son actually really liked this and felt it would help him with his memorization of multiplication facts, however to get the other numbers (3x, 4x, 5x, etc) you have to pay .99 per number. To get all the math facts to 11 you have to pay almost $9.00! That's ridiculous. Put all of them into ONE app and just charge me 4 or 5 bucks. You would be alot more likely to get my money.

Fantastic App


I got this app to help my 2nd grader get a head start on her multiplication tables. After about a week, my 4 year old can now also spit out his 2x tables, count by 2's and has great number recognition. I am about to purchase the full multiplication library - LOVE THIS APP!
