Title: Good Value for Money, but Math Shark is Better
Review: I have an 8 year old and an 11 year old. I ordered this and the Math Shark. The Shark is about twice as much, but both of my children prefer the Shark. The Shark appears to be more challenging and cover a wider range of problems. If your child is over 10 I would choose the Shark. If not, this is a good value. I give this 4 stars because of the value proposition. The Shark would get a 5 star rating.
