摘要

The present invention relates to a teaching tool having a straight flexible pipe for learning, which is manufactured with the constant size of a circular pipe form by using polypropylene (PP). The teaching tool comprises: a straight teaching tool connection member (100) having a pair of coupling tubes (120) and a wrinkle tube (310) formed with a plurality of wrinkles to have flexible functions; and a connection tube (200) equipped with a pair of truncated connectors (210) for connecting the straight teaching tool connection member (100) by one and for displaying a scale (220) to previously predict the size of the teaching tool by a user. The teaching tool is capable of being freely bent, manufacturing a teaching tool for learning various shape desired by the user, and adding learning effects with respect to various figures and the interests in mathematics.
