1 Teach children to learn and correctly judge numbers within 7 without being affected by the arrangement of objects. Ask the children to listen to the teacher's questions clearly and answer them loudly in front of the group.

Preparation: The teaching AIDS are pasted with 5 large blue disks, 6 small red disks, 7 small orange disks (Figure 1), numbers 5, 6 and 7, and physical cards (Figure 2-8). The first and second groups of learning tools: 3 rows of braille cards (Figure 9), digital seals, inkpad and children's books.

Process: 1 group activity.

(1) Show pictures 2 to 8 one by one. "Please look at the children carefully and tell me what is written on the card?"

(2) Correctly judge the quantity within 7.

Show the diagram 1, "What's on the blackboard?" "What kind of color wafer is the most? Which color has the fewest discs? how do you know Why do you think there are the most red plates and the least orange plates? Who can think of a way to change-the planting method will make children see at a glance, who has the largest number and who has the least number. "

(3) summary.

"If you want to know who is more and who is less, you can't look at the size of the object or the length of the queue. Just count-count how many there are in each row, so as to compare who has more and who has less. "

2 Group activities.

One or two groups, print out the numbers with the most ideas. Group three, look at the signs and put up pictures.

Four groups, fill in the blanks in order. Five groups, add or delete ideas.

Six groups, printed fewer ideas than 6 and 7.

Teachers focus on guiding the first and second groups [1][2]
