Description

A middle school mathematics number-shape combination mathematics auxiliary device for education

technical field

The utility model relates to educational equipment, in particular to an educational auxiliary device for combining mathematical numbers and shapes in middle schools.

Background technique

In the teaching process, mathematics teachers need to use teaching documents such as teaching plans and drawings, and at the same time need to use planning tools such as rulers, set squares, and protractors, so that students can fully understand what they are learning, while mechanical teaching is difficult for students to understand , so it fully demonstrates that the teaching method of combining numbers and shapes in modern middle school education is very important. Usually, teachers need to draw pictures according to the mathematical formulas in the teaching plan during class to help students understand, but drawing takes a long time, and Sometimes there are many diagrams that need to be made, occupying a lot of space on the blackboard, but there is less space to write formulas during subsequent algebraic analysis, and sometimes it looks very messy, so it is very inconvenient.

Although the "Mathematics Teaching Auxiliary Device" disclosed in CN 204432121 U improves the work efficiency of teachers to a certain extent and reduces the workload of teachers, the ruler used for teaching is exposed to the outside for a long time and is used.
