产品名称：益智七巧板 700个一箱

产品产地：浙江

产品尺寸：11.4*11.4*0.7cm

产品重量：0.035kg

注意：几毛钱能买到的东西真的不多了！这款七巧板适合淘宝卖家做赠品使用，质量做工不完美，主要是便宜，亲们对质量不要抱过高的期望，不要买回去之后说怎么这么差！如果以没有想象中好，可以退回，运费自付！！

七巧板又称七巧图、智慧板，是汉族民间流传的智力玩具。它是由宋代的宴几演变而来的，原为文人的一种室内游戏，后在民间演变为拼图板玩具。据清代陆以湉《冷庐杂识》说：：宋黄伯思宴几图，以方几七，长段相参，衍为二十五体，变为六十八名。明严瀓蝶几图，则又变通其制，以勾股之形，作三角相错形，如蝶翅。其式三，其制六，其数十有三，其变化之式，凡一百有余。近又有七巧图，其式五，其数七，其变化之式多至千余。体物肖形，随手变幻，盖游戏之具，足以排闷破寂，故世俗皆喜为之。”现七巧板系由一块正方形切割为五个小勾股形，将其拼凑成各种事物图形，如人物、动植物、房亭楼阁、车轿船桥等，可一人玩，也可多人进行比赛。利用七巧板可以阐明若干重要几何关系，其原理便是古算术中的“出入相补原理”。 undefined
