{"product_id":"yohaku-book-2-mike-jacobs-9781093415209","title":"Yohaku Book 2","description":"Yohaku(TM) is a new type of number puzzle created by Mike Jacobs. THis second book of puzzles will test your number sense and problem solving skills. Each yohaku is either an additive or a multiplicative puzzle (as indicated by the symbol in the bottom right of the grid). Your task is to fill in the empty cells such that they give the sum or product shown in each row and column. Yohakus are great for use in classrooms as a lesson starter, or for the morning commute, or for something to accompany an afternoon cup of tea. Some yohakus will take a few minutes to solve, others will have you puzzling for longer.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Mike Jacobs\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 1093415207\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9781093415209\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Independently Published\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 04\/16\/2019\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 86\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.21lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 8.00h x 5.00w x 0.18d","brand":"Mike Jacobs","offers":[{"title":"Paperback","offer_id":43923981369599,"sku":"9781093415209","price":6.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/products\/img_e24f04be-6213-4b9b-85a3-e920b583ed4a.jpg?v=1681067791","url":"https:\/\/www.whiterainbookhouse.com\/products\/yohaku-book-2-mike-jacobs-9781093415209","provider":"WR Book House","version":"1.0","type":"link"}
