Mathematics activity in kindergarten middle class: model snake
Can identify relatively complex arrangement patterns AABAABAAB. Let's take a look at what I've arranged for you: math activities in kindergarten middle class: mode snake, welcome to read, for reference only.

Mathematics activities in kindergarten middle class: model snake teaching materials and children's experience analysis: in small class mathematics activities, it is found that children have mastered the alternating sorting activities of one-by-one, one-by-two and one-by-one. In this math activity, we focus on learning to copy AABAABAAB mode with toy cards, and try to expand the new modes ABABABABAB and ABABABABABABABABABAB.

Activity objectives:

1. can recognize the relatively complex arrangement pattern AABAABAAB.

2. Try to copy and expand this model with toy cards.

Highlights and difficulties of the activity:

Master AABAABAAB arrangement mode.

Activity preparation:

Model snake (toy card)

Activity flow:

(1) Children observe the two patterned snakes strung together by the teacher and know the pattern AABAABAAB.

The teacher showed the small snakes strung together. The mode is AABAABAAB. Let the children observe and say what is the law of small snakes, such as:

1. Does this little snake have a regular body color? What is the law?

2. The body of this little snake is strung according to the rules of yellow, yellow, yellow, yellow and yellow.

Show another small snake, the pattern is still AABAABAAB, and the colors are green, green, green and yellow, so that children can observe and think, such as:

1. Does this little snake have a regular body color? What is the law?

The body color of this little snake is strung according to the rules of green, green, yellow, green, green and yellow.

Both small snakes have yellow and green, but they are arranged in different ways.

(2) Children make several patterned snakes with toy cards, copy and unfold the pattern AABAABAAB.

Please take out your toy card and take the materials away. First, imitate a small snake made by the teacher, such as a small snake with yellow, yellow and green rules, and string out at least 9 bodies, that is, 3 groups. Children in the same group verify with each other whether they are doing the same as the teacher. For example:

1. Is your little snake the same as the teacher's? Why?

Its body is yellow and green, just like the teacher's.

When the children finished, they imitated and made another snake with yellow, yellow, green and yellow body colors. At least nine bodies were also strung out, and the children in the same group verified each other.

(3) Encourage children to expand or create new patterns after they identify and copy AAB patterns.

Give children free time to create, and continue to complete the operation of two small snakes with the remaining materials, that is, expand the model.

Encourage children to dismantle the small snakes that have been strung, and make new models with yellow and green materials, such as ABABAB and ababab.
