As one of the top online toy retailers, we have access to unprecendented quantities of product review data. One of the key ways that we use this data is by associating our products to the specific ages and genders of the kids who are playing with them. Whereas most retailers must rely upon manufacturer suggested ages (i.e. 3+), we take actual customer usage and share it with you here so that you can choose the perfect toy or game.
But how does this help me? You can use these graphs as a general measure of it's appropriateness for a given age and gender. While this information is generally accurate, it should not be used as an absolute answer. For instance, many dinosaur toys are purchased for boys, however, that doesn't mean that it's inappropriate for a girl who happens to like dinosaurs.
NOTE: The orange color in the charts above indicate ages that are LESS than the manufacturer suggested age. Please purchase at your discretion if your child is younger than 9 years of age.
Purchased to assist a 9 year old in understanding math. The relationship between understanding math and using this device was obscure for us. The item was returned.
We gladly assisted. If your satisfaction doesn't prove exceptional, contact us! Our customer service crew takes pride in adding to your joy, subtracting your worries, multiplying your good experiences, and dividing things like cupcakes. Please visit the Returns & Exchanges center for details.
I like this product. It provides my child with a math challenge she does not get in school. She will pick it up and do 1 or 2 puzzles every so often and then come back in a day or so. I think it will be used for next few years as her abilities grow.
Review of Aba-Conundrums
Posted 8/3/2010 by WILBUR BOOTH
Grandson enjoyed this as much, or more, than his Legos. He is 10 years old and in advanced placement classes. This fit the bill for his analytical skills and problem solving tendencies. He loves challenge and this presented one. Interestingly, it opened up a whole new range of activities he could create. At dinner, without the game, he used the concept to create a "problem" for his Dad to solve. His Dad then created one for him.
A rating of Aba-Conundrums
Posted 7/8/2010 by Ronald Knarr
An instruction manual that showed how the product could be used for doing basic math functions would have helped I believe. If the product could be used for higher functions an explanation of how that is done would have been good.
The nature of this product is to provide fun math & logic puzzles to stretch your thinking. Please note that Aba-Conundrums is not intended to teach how to add, subtract, multiply, and divide on the abacus. Although it can certainly be used for that purpose by incorporating abacus information readily available in many books and on the internet. We promise to keep your trust in offering products that are especially unique. If any Fat Brain Toy is different than expected, we will slide right in to help.
