Design intention: Small class children are easily dominated by external things and emotions in the cognitive process. Inadvertent memory is dominant, and people tend to remember things unintentionally. Games and operations are children's favorite activities. If children simply know the circle, they will feel bored, their interest is often not high, and the effect is not good. Therefore, when designing this kind of teaching activity, let children know some common round objects and features in the game operation, so as to stimulate children's interest in observing and exploring things around them and develop their abilities of perception, observation and imagination.
Activity objectives:
1, can grasp the characteristics of the circle in cognition, operation and game activities.
2. Be able to find circular objects in the surrounding environment and perceive the application of circles in life.
3. Cultivate children's observation and imagination.
Activity preparation:
1, the activity room is decorated with some round objects.
2. A round piece of paper and some round objects (such as mirrors, bottle caps, tambourines and plates).
3, slides, each table has a box, there are all kinds of round items in the box, some operation paper, a marker.
Activity flow:
First of all, create a situation and know the round object.
Teacher: (with mysterious tone and eyes) Today, the teacher brought a box of toys to the children. Please take one to play on the table. What is this?
The mirror I took,
I took the tambourine,
Yang: I took the plate. ...
Teacher: What did you find? What do these things have in common?
Yang: They are all round. (bring up the topic of the circle. )
Teacher: (showing a round piece of paper) Question: What is it like?
Yang: It's like a plate.
Yang: Just like the sun.
Yang: It's like …
Second, the characteristics of perception circle.
Teacher: Let children choose a round object and touch it along the surface and edge of the object to exchange feelings with each other.
Young: generally,
Young: round,
Yang: The edges are smooth.
Young: no edges and corners ... (children communicate and fully express their views)
Teacher: Tell me, what else have you seen that is round? Encourage children to tell the round things they see at home or elsewhere.

Teacher: Have a look. What shape are the wheels of a unicycle? What else is round?
Young: round, (children say together)
Yang: And balls, hula hoops, rolling circles and plates.
Fourth, make a circular mark.
Give each child a piece of white paper (with a circular hole around it), guide the children to tear it into a circle along the hole, and then let the children draw something they like on the circular paper or make a mark, and then stick it on their own things as a sign.
Five, looking for round items
Guide children to look for round objects in the activity room and ask them to express them with words such as "I found them: they are round". And put it in the math activity area regularly.
Activity expansion:
Prepare some paper with circles for your child, inspire your child to add a few strokes to the circle and turn it into another pattern (such as the sun and apples), and encourage him to draw as many as possible.
