moving target
1, willing to participate in the formation of 6 activities and experience the fun of the activities.
2. Be able to take different quantities of materials within 6 days as needed, and think positively and concentrate on the operation.
3. Learn the composition of 6 and understand the relationship between numbers 5 and 6: 1 more, 1 less.
4. Cultivate children's comparative judgment ability.
5. Guide children to actively interact with materials and experience the fun of mathematics activities.
Activities to be prepared
1, each person has 6 different kinds of leaf cards, 1 set of numbers 5 and 6 cards, 1 dice (6 faces have 1-6 ideas respectively).
2. Four solid leaves, four point cards 1, five apple cards and six pear cards.
Emphasis and difficulty of the activity
Focus of activities
The formation of learning.
Activity difficulty
Understand the relationship between numbers 5 and 6: 1 and 1.
Activity process
First, be familiar with the materials and satisfy children's curiosity.
Observe leaves and digital cards. Communication: How many leaves are there? Do you know the numbers on the card?
Teacher: There are leaves of different shapes and colors on the plate. Please count the leaves. Do you know the numbers on the card?
Second, the game-compare who did it right and review the formation of 5.
Teachers show four physical leaves, four dot cards and five digital cards at a time, and ask children to operate the leaf cards according to the different guidance of the physical objects, dots and symbols, and review the composition of numbers within 5.
1. Please take out as many leaf cards as there are on the blackboard (4 cards).
Can you make four leaves as many as five? How did it change?
Summary: Four leaves plus 1 becomes five leaves, and four leaves plus 1 is five.
Third, guide children to reason, operate and learn 6.
1, inspire children to think and operate leaf cards, and match the corresponding numbers: think about it and try. How to change five leaves into six leaves?
Summary: acanthopanax pentaphyllum 1 chengliu, acanthopanax pentaphyllum 1 chengliu.
2. Teachers demonstrate five apple cards and six pear cards on the blackboard one by one to guide children to perceive and understand the quantitative relationship between five and six, which is greater than 1 less than 1.
Count: How many apples are there? How many pears are there? What figures were used respectively? (Teaching plan. From: lesson plan network) Who has the largest number? How much more? Whose number is small? How much is missing?
Give it a try: How many ways can you make two kinds of fruits as much?
Summary: There are two ways to make as much fruit as possible.
The first method is: five apples plus 1 become six, and six apples are as many as six pears.
The second method is: six pears are reduced from 1 to five, and five pears are as many as five apples. 5 is 1 less than 6, plus 1 becomes 6, 6 is 1 greater than 5, and minus 1 becomes 6.
Fourth, the game-compare the size, consolidate the understanding of numbers within 6, and feel the fun of mathematics.
Ask two children to play dice. Whoever throws more laps wins. The loser holds a digital card. The teacher guides the children to review the composition of numbers within 6.
Activity expansion
Look for 6 items in the classroom.
Activity reflection
Children can basically distinguish size and color in activities, but some children can't express it clearly in the right language. The last part of the activity is to consolidate children's classification according to color through games. This activity has strong plot, interlocking links and strong participation of children, which makes children's learning change from passive to active, and children unconsciously gain classified experience and improve their observation and comparison ability in interesting activities. During the whole activity, the children's activity enthusiasm is very high. Improve children's operation ability and skills in the activities of hand, brain, mouth and eyes.
