"Understanding Spheres and Cylinders" Kindergarten Large Class Mathematics Teaching Plan
As a selfless teacher, writing lesson plans is essential. With the help of lesson plans, teaching methods can be properly selected and used to arouse students' learning enthusiasm. How to write the lesson plan? The following is the math teaching plan of "Understanding Spheres and Cylinders" compiled by me. I hope it will help you.

moving target

1, through touching, measuring, rolling, comparing and other activities, we can know the sphere and cylinder and distinguish their similarities and differences.

2, improve the ability of observation, comparison, imagination, analysis, synthesis and hands-on ability.

3. Develop interest in exploration and develop creativity and thinking ability.

Activities to be prepared

1, prepare various balls. Such as ball, basketball, football, table tennis, glass ball, shot put, plastic ball, etc.

2. Prepare some cylindrical toys. Such as building blocks, plastic products, sticks, unused pencils, kaleidoscopes, etc.

3. Video about spheres and cylinders.

Activity process

First, ask the children to guess a riddle.

Fat, round, untenable, unstable, either side will roll. (sphere)

Teacher's summary: Many balls, although different in color, size and playing style, are all the same in shape. No matter which direction you look, it is round. They are always unstable and rolling on the ground. This is a ball.

2. Let the children measure an unused pencil, stick, kaleidoscope, etc. Look at the size of the circles at both ends and the distance between the two circles with lines, rulers and small hands, and talk about their findings.

Third, the teacher summed up: when measuring, there are two circles with the same size at both ends, and the vertical distance between the two circles is the same; When scrolling, you can only scroll in two opposite directions; Arranged vertically, it looks like a pillar. This is a cylinder.

Ask the children to take two toys (a ball and a cylindrical toy) and roll on the ground in the same way to see if they are different and can stop and stand firm.

Five, guide children to try to overlap two spheres and two cylinders, and observe the phenomenon.

Sixth, the teacher summed up: the sphere can roll in all directions, and the cylinder can only roll in two opposite directions; There are no planes on the sphere and they cannot overlap. There are two equal planes at both ends of a cylinder, which can overlap.

Seven, let children think about it, in kindergarten, home or other public places, what are the spheres? What is a cylinder? Talk about their names and functions respectively.

End of activity

Watch the video of spheres and cylinders.
