"Lotus in full bloom" is a mathematical activity with the theme of "Summer is coming" in experiential textbooks, and counting a circle of lotus flowers is the focus of this activity. I have compiled the following contents: "Small Class Mathematics Teaching Plan: Lotus in Full Bloom" for your reference!

Small class math teaching plan: "Lotus in full bloom"

Design intent

In order to let children determine the starting point, the activities adopt the methods of finding problems, exploring independently and solving problems, and support and encourage children to determine the starting point when obtaining the number of cycles through independent exploration. There are two levels in the process of guiding children to find a starting point. The first level is to determine the circular arrangement diagram of objects with different starting points by comparing similarities and differences, and the second level is to determine the circular arrangement diagram of objects with the same starting point by means of auxiliary means. The organization of the link adopts the strategy of children's independent exploration-* * * communication-teacher's promotion, which effectively mobilizes children's learning interest and enriches counting experience.

Teaching objectives

(1) By determining the starting point, try to count the objects arranged in a closed loop, and enrich the counting experience.

(two) can carefully observe the picture, according to the characteristics of things or with the help of auxiliary tools and other methods to identify the starting point.

difficulty

Key point: Learn to count the objects arranged in a closed loop by determining the starting point.

Difficulties: Explore various methods to determine the starting point.

Teaching preparation:

(1) Picture 1: 10 Lotus flowers with different characteristics arranged in a ring; Figure 2: 10 Identical lotus flowers are arranged in a circle. (One picture for the children, and one for each of the other pictures in a circle. )

(2) pens, clips and paper clips.

teaching process

Lotus flowers bloom in June.

1. Meet the Lotus

-What kind of flower is this? Do you know him? (Teacher shows pictures 1)

Independent counting

Please count how many lotus flowers are there in this star?

Exchange discussion

-How many lotus flowers are there? Let the children talk about the results of their own counting. ) Who will count? Ask some children who count wrong to demonstrate and interact with them. For example, if you start counting from the basket, why don't you stop counting? )

Do you think he can count like this? Why? How to count so as not to repeat? (Guide the children to communicate, ask several pairs of children to communicate and demonstrate their own methods. )

(Teacher's summary) When counting things in the circle, remember which flower to start with, so as not to make a mistake.

(2) blossoming lotus blossoms.

1. Learn to find the starting point according to the obvious characteristics of things.

Which flower do you want to use as a starting point? How can I remember that this flower is the starting point? (Guide children to exchange their ideas independently. )

(Teacher's summary) As long as we observe carefully, we will find that these lotus flowers are different. We can determine the starting point according to the color, shape or position of the lotus, which is easier to remember and won't be repeated.

2. Learn to find the starting point by marking.
