Before teaching activities, teachers inevitably need to compile teaching plans, which are the main basis for implementing teaching and play a vital role. Come and refer to the lesson plan you need! The following is the math teaching plan for the kindergarten big class that I helped you organize: Is there as much water? Welcome to share.

Activity objectives:

1. Try this experiment to gain experience about capacity conservation.

I am willing to explore the change of water and understand its main characteristics.

Activity preparation:

1, fun exercise: ability comparison

2. bottles marked with scales, water, recording paper and pens.

Activity flow:

First, observe and ask questions.

Teacher: Let's have a look. Are these six bottles of water the same? how do you know

Conclusion: Now let's try to do an experiment and compare the water quantity.

Second, the experimental operation

1. Teacher: How to verify it? How to operate?

Requirements: The two bottles of water used in the experiment should not be mixed together, and the action should be slow during the experiment, so as not to spill the water and affect the experimental results.

2. Record the experimental results

(1) The method of two bottles with different heights is to compare the water levels, and we can see that the water in the bottles is the same.

It turns out that the height of the bottle does not affect the amount of water.

(2) Choose two identical empty bottles from two bottles with different thicknesses, and pour the drinks from the bottles with different sizes into them, and there will be as many drinks as there are.

Methods: Choose a bottle, pour a bottle of beverage, mark it with strokes or sticky paper, pour a bottle of beverage into the bottle after pouring the beverage, and see if the position of the beverage is consistent with the original mark. Comparing the thickness of the original bottle does not affect the water quantity.

(3) The contents of the bottle containing the contents are stones. The method is to take the stones out of the bottle and compare the water level.

The contents are sponge nodules: the method is to squeeze the water in the sponge back into the bottle and compare the water levels.

It turns out that whether there is an object in the bottle does not affect the amount of water.

3. Summary: The height, thickness and contents of the bottle do not affect the water quantity. This phenomenon is called capacity conservation.

Third, activity extension. Think about it. If you put two pieces of plasticine with the same weight into bottles with different shapes, will the plasticine become heavier?
