1. Match items with the same shape.

2. Preliminary perception of three-dimensional graphics.

3. Like to pile up and develop ideas.

Activity form: group

Activity preparation: building blocks and cloth bags.

Activity flow:

1. Show building blocks with different three-dimensional graphics. Let the children touch, let them count their faces and try to build different combinations.

2. Let the children freely form a group of three and play matching games together. The teacher put three or four blocks in the bag first, and then distributed the bag to each group of children. After receiving the bag, please take out the building blocks and observe them carefully, then go to the activity room to identify the items with the same shape and put them into the bag.

3. Let each group of children take out the collected items and compare them with the building blocks to see if the shapes are correct. Then use these objects to create piles.

4. Ask each group of children to introduce the name and content of their works.

Please ask the children to put the things in the bag back.

Summarize and share:

Please tell the children where they found those things.

Activity evaluation:

1, you can pair items with the same shape.

2. Different items can be used for stacking creation.

Activity suggestion:

1, the teacher should adjust the difficulty of this activity according to the actual development level of the children in this class. For example, the main features of the building blocks in the cloth bag are obvious, which is convenient for children to pair. When children are quite familiar with the matching game, it will gradually increase the difficulty, such as letting children find multiple items with different colors and sizes but the same shape.

The concept of "three-dimensional graphics" is still difficult for a small class of children. Teachers can let them know their differences by comparing "cubes" and "squares".

3. Guide children to play various matching games in their daily lives, such as finding the same pattern in a wall chart by connecting lines.
