Today, the content of my class is "how much to count" the math activities in the middle class. This activity takes the mother duck and duckling playing hide-and-seek as situational clues, and encourages children to master the numbers within 7 by using the methods of visual inspection and hand-mouth coincidence.

On this basis, observe the different characteristics of ducklings with children, help children summarize and sort out scattered perceptual experiences, clearly highlight the characteristics and quantity of objects, and make children feel the quantitative relationship contained in objects, thus forming a preliminary concept of number and promoting the development of thinking ability.

Before the activity, I prepared an interactive courseware for the children. Through the picture of ducklings playing hide-and-seek on the farm, some ducklings are hiding in the grass and leaking flowers, and some ducklings are hiding behind and leaking a foot, so as to achieve the purpose of correctly judging the numbers within 7 by visual inspection or counting.

According to the different characteristics of seven ducks, such as three red mouths and four yellow mouths; Only wear a Chinese-style chest covering, only wear a Chinese-style chest covering and so on. To realize the relationship between numbers in observation, comparison and classification.

The following simulation activities officially began: playing courseware and eliciting activities; Children's operation, teacher's guidance; Collective inspection and re-operation; Observe and compare, classify; The situation runs through and ends the activity.
