Teaching aid of rotary -type understanding shape

The utility model relates to a teaching aid of rotary -type understanding shape, including base, pivot and building blocks body, the base is the square structure, cuts apart into three relatively independent and big or small equal rotator extremely down on the follow, and the side of every rotator is equipped with the recess, the building blocks body sets up a plurality ofly, have at least a building blocks body can with the recess inlays the dress, the center of base is equipped with pivot, the enough relatively independent rotations of rotator homoenergetic. Rotatory main part lets plays teaching aid in use and is full of more possibilities, cause child's curiosity and the intention nature that increases child, has solved building blocks problem of perception single on the market, can risk various geometric figure through rotation, the building blocks that make up at random, and convenient to use possesses fine educational value. 本实用新型涉及种旋转型认识形状的教具，包括基座、转轴和积木本体；所述基座为正方体结构，从上至下分割成三个相对独立且大小相等的旋转体，每个旋转体的侧面设有凹槽
