Height comparison (top class science field) Activity goals 1. Children try height comparison methods and explore the fastest way to compare heights.

2. Learn to record the results of exploration on a note card.

3. Able to cooperate with peers.

Activity preparation: A schedule designed by the children themselves; a small symbol for each child; a red, yellow, and blue record card; a height stick for each child; a grid board; 1-12 number cards.

Activity process 1. Show three plans designed by children, and the teacher asks: 1. What are the children in the pictures doing?

2. How can you compare heights?

(Back-to-back comparison, comparison with the grid, comparison with the teacher, asking a child to see who is taller and who is lower) 3. How do you want to compare the heights of the red and red groups?

4. How do you want to compare the heights of the yellow and yellow groups?

5. In the Blue and Blue groups, what method do you want to use to compare heights?

6. Which method is the best?

Children, follow your plan and give it a try.

2. Children’s experimental operation exploration, teachers provide guidance in groups.

After the children compare, record it on the record card.

1. Who is the tallest in the red group?

Who is the shortest?

2. Who is the tallest in the yellow-yellow group?

Who is the shortest?

3. Who is the tallest in the Blue and Blue groups?

Who is the shortest?

4. The children are really capable. They compared the tallest and shortest children in each group. Short children, don’t feel bad. As long as you eat well, are not picky about food, eat more nutritious food, and keep exercising, you will soon be good.

Will grow taller.

We just used so many methods to compare heights. Which method is the most convenient?

Why?

5. Just now we compared the tallest children in the red group, yellow-yellow group, and blue group. So, how to compare the tallest children in the three groups?

6. Where should the symbol of the tallest child be placed?

7. We use different methods to compare the shortest children among the three groups.

8. Where should the symbol of the shortest child be placed?

9. We have compared the tallest and the shortest children. There are 6 other children. How do you want to compare?

10. Where should the symbol of the tallest child among the 6 children be placed?

(Compare the following ones in turn) 11. What is the fastest and most convenient method we use?

12. Take a look, where are you?

3. Games Teacher: Children, remember where you are in the ranking. We will form a line from high to low.

Reflection on the Activity During the theme activity of "Our Body", the children became very interested in their own bodies, their growth and height. Some said that they could no longer wear the clothes they had when they were young, and some said that they could not wear the clothes they had when they were young.

He said that now he can reach things that he could not reach before.

So, I consciously put in the measuring paper for measuring height. As a result, the children were very interested in it, and there were more and more topics about their own growth and height. Therefore, I felt it was necessary to carry out a group activity to let the children work together.

Share your discoveries and experience the joy of growth together.

At the same time, I integrated the number activities of comparing heights and sorting into teaching activities, so that children can accumulate some methods of comparing heights and sorting by heights by measuring and comparing with their peers, so as to further experience the joy of growing up.

.

I also use various methods such as playing games and appreciating prose to stimulate children's desire to grow taller, and strive to achieve integrated educational goals and promote children's development.
