★Having learned so much about koi fishes, do children want to play with koi fishes?
★Next, let’s play a game of “catch carp”. (The teacher turns on the voice of the help content in the courseware) Let’s listen to how this game is played.
★Now ask each child to find out the fish tank from his toolbox, and “catch” the koi fishes in the water lily pond into the fish tank.
★Count after completion, how many of each color, how many groups add up, and record the total. The group members line up the fish tanks together to see which tank has the most koi fishes of each color and which tank has the least.
Activities can be varied
1) Children’s independent activities. After the completion, count the number of koi fishes of each color in the group, calculate the total, and try to record the results.
2) Carry out activities by goal, such as:
According to the number of koi fishes: the group catches 30 koi fishes together.
According to the number of fish tanks: find 4 fish tanks for each group to play.
According to color 1: the first and third groups catch red and white ones, and the second and fourth groups catch orange and black ones.
By color 2: Each group catches koi fishes of two colors.
According to the pattern: the first and third groups catch patterns, and the second and fourth groups catch solid colors.
According to the direction: the first and third groups catch koi fishes that swim from the teacher’s right hand to the left hand side, and the second and fourth groups catch koi that swim in the opposite direction.

Interesting method 1: The first and third groups catch koi fishes passing under the water lily, and the second and fourth groups catch koi fishes in the center of the pond and those that have not passed under the water lily.
