My kids love this. I must confess that they don't always use it as designed. Frankly, just slapping the things is pretty darn fun for a 5 and a 3 year old. My 5 year does get to use it as its designed a bit. There are 5 different games on it. One where you put the numbers in order, one where you add two numbers together, one where you subtract one number from another, one set up in an algebraic way (4 + ? = 6), and the last is called triple slam. In triple slam, there are 3 numbers to add or subtract -- ex. 9 + 2 - 3 = ?
The volume level goes from nice and quiet to not super annoying. The constant banging can get annoying for me (I have a noise thing), BUT the game is super durable and withstands all the banging/slamming. And there is a headphone jack if quiet is necessary -- or you have multiplication going on in the car at the same time.
We are a homeschooling family and this is one of the learning toys that I allow them to get out on Monday's which is our game day. It's also a great car toy and because we have 3 similar ones, there are even enough to go around (Math Slam, Math Shark & and Multiplication Slam). I recommend it to anyone who would like to ensure their children's mastery of the math facts, whether you are in in public, private or home school. You can only do so many worksheets and flashcards. This is great for independent practice.
