Rich ski equipment can attract the attention of primary school students, stimulate their interest in learning by using their fun, and enable students to exercise their thinking ability and form good hands-on ability through hands-on operation.

Teaching AIDS that can be used in the second grade of primary school mathematics include

I. Tangram

Tangram is used in grade one, but which figure will be used in grade two when learning corners? How many line segments are there? Or each figure has several acute angles.

Second, the triangle

The second grade has begun to learn the basic knowledge of angle. Triangle can be used to judge right angle, acute angle and obtuse angle. Triangles are necessary.

Third, clocks and watches

The time for senior one to learn specific clocks is different from that for senior one. Senior one only learns half an hour on the hour, and senior two is more detailed, so the virtual child has a model table.

Fourth, the multiplication table

The second-grade children have learned the multiplication formula, and some children have trouble memorizing it, so it is necessary to have a multiplication table, which can be previewed at any time, or review can help children remember better.

These are probably the math teaching AIDS for the second grade. I hope I can help you.
