{"product_id":"math-snake-wood-puzzle-for-kids","title":"Math Snake 7 Wood Brain Teaser | Math Puzzle for Kids","description":"\u003cp\u003eI love math puzzles, and with the help of Ken Irvine of NJ, we came up with the Math Snake idea. The idea is to rotate them until there is a correct equation on all 4 sides of the blocks. The equation is read from left to right, irregardless of operation priority.\u003cbr\u003e\u003cbr\u003eThere is a 7 block model (here) and also a more difficult 9 block model offered on a different listing. They are high quality all wood construction with deeply burned laser engraved numbers from our shop in Hudson, FL. The blocks stay as a string but will rotate individually. The 7 block model may look easy, but its not really as there are 1024 possible permutations of the blocks, but only ONE correct solution. (Note on the 9 block version there are 16,384 permutations but only 1 correct solution.) \u003cbr\u003e\u003cbr\u003eKen Irvine wrote the program to develop the math layout on the blocks. As it turns out there are a number of possible ways to burn the numbers on the blocks and still have a unique solution. So there are 20+ different models we can offer on each of the 7 block or 9 block models. If you are a school teacher or puzzle enthusiast who wants more than 1 snake with each one being different I can do that for you! Just let me know how many different ones you want.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Creative Crafthouse","offers":[{"title":"Default Title","offer_id":50680621170872,"sku":"MathSnake7","price":9.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0642\/1125\/5480\/files\/math-snake-7-wood-puzzle-learn-and-teach-elementary-grade-math-gift-for-kids-gifts-under-10-dollars-creative-crafthouse-500211.jpg?v=1762101404","url":"https:\/\/www.creativecrafthouse.com\/es\/products\/math-snake-wood-puzzle-for-kids","provider":"Creative Crafthouse","version":"1.0","type":"link"}
