As a people's teacher who specializes in teaching people to solve doubts, he usually needs to use teaching plans to assist teaching. Teaching plan is the basis of teaching activities and has an important position. So, have you studied lesson plans? The following is my collection of math teaching plans for kindergarten middle class: Understanding Trapezoids, for reference only, welcome to read.

moving target

1, guide children to learn through operation, and know the trapezoid to stimulate children's interest in learning.

2. Cultivate children's observation ability, comparison ability and abstract generalization ability.

3. Grasp the basic characteristics of the reminder and find the trapezoid according to the characteristics.

Activities to be prepared

1. Courseware: two slides and a bear picture.

2. Each person has a piece of red rectangular paper and yellow trapezoidal paper, a stick and a graphic paper (printed with China objects).

Activity process

First, import

1. Let the children think and understand the concept of parallelism in the tone of visiting the kitten performance.

The teacher plays the courseware and two kittens race.

Put forward a thinking question: did the two kittens really meet when they ran to the finish line? Why? "

2. Summary: Because the running route of kittens is flat, they will never touch each other.

The distance between the upper and lower lines like this, like the first small bridge, is the same length, which is called parallelism.

Second, expand

1, children's operation perception

Please pay attention to the children. How many pieces of paper are there on your desk? What shape is it? Overlap two pieces of paper and see what they have in common. What is the difference?

Summary: Similarities: they are all four sides and four corners.

Difference: the two opposite sides of a rectangle are parallel and equal in length, and the four corners are equal in size;

The upper and lower sides of another figure are parallel, but the length is different, and the other two sides are oblique.

2. Let the children operate the perception again according to what the teacher said. Remind children to measure and compare with a stick. Get the teacher's grades.

And tell the child again that if the distance between the upper and lower sides is equal, we say that the two sides are parallel.

3. Summarize the concept of trapezoid: there are four sides and four corners, and only one set of opposite sides is parallel and unequal in length.

This figure is called a trapezoid.

4. Consolidate the understanding of trapezium and show the following figures: Guide children to name the figures after observation and comparison. Why?

Third, the end.

Children's coloring: Please paint the trapezoid in the drawing with your favorite color.
