Description
算数教育用の教具であって、
平面視矩形状に形成された中空筐体状の部材であって、その長手方向の両側面が開口したケースと、
同じく平面視矩形状に形成された、上面が開口する容器状の部材であって、仕切部により、内部領域がその長手方向の左右両側にそれぞれ平面視矩形状の領域を形成するように仕切られてなり、前記ケースの長手方向両側から引き出し可能に前記ケースの中空部内に収容される引出部材と、
前記引出部材の内部領域内に配置される複数の球体とを備えてなり、
前記引出部材の各内部領域は、該引出部材の長手方向に少なくとも一列に5個の前記球体が並ぶように形成され、
前記引出部材の仕切部は、前記各内部領域同士を連通させる、少なくとも1個の前記球体が通過可能な連通部を有し、該連通部を通して一方の内部領域内にある球体が他方の内部領域内に移動可能に構成された算数教育用教具、及びこれを用いた算数教育方法に係る。
