Activity design:
According to the characteristics of intuitive thinking and action of middle school students and their psychological characteristics of playing games, being active and curious. Mathematics activities should be closely linked with children's real life. By choosing the things that children are interested in in life as the objects of exploration activities, we can feel the calculation of life forms and the quantitative relationship in exploration, and experience the importance and fun of mathematical activities. In this lesson, we visit the orchard and vegetable garden of the little white rabbit's house to stimulate children's interest in learning mathematics, and let them perceive the corresponding relationship between numbers 8 and 9 and numbers and quantities in happy and interesting activities. And contact the combination of numbers and objects within 9 to cultivate children's counting ability in the game.
Activity objectives:
1, understand the practical significance of mathematics 8 and 9, and perceive the corresponding relationship between numbers and quantities in activities.
2. It can get numbers from multiple objects one by one.

Activity reflection:
In this lesson "Combination of Counting and Things in August and September", we took our children to visit the orchard and vegetable garden of the White Rabbit, which not only taught them to count things, but also reminded them to eat more fruits and vegetables for the sake of our health.
At the beginning of the activity, I first reviewed the "combination of numbers and things of 7" I learned last class, and the children mastered it very well. Therefore, when they enter the "combination of numbers and things of 8 and 9", they can easily grasp it and quickly express it with several points and numbers according to things.
In the process of teaching, my thinking is still very clear, but there are some mistakes in quantifiers, which need more attention.
In the process of learning, children are very active in thinking, actively answer questions and finish their homework well.
