Interesting mathematical design of mathematics activity measurement in kindergarten large class.
Activity objectives:

1. Feel and experience the meaning of distance, and stimulate children's curiosity and inquiry spirit.

2. Learn to measure the distance with tools and record the measurement results in a table.

3. Initial perception of the same distance, different measuring tools, different measuring times, the same distance, different tools, different measuring times, the longer the tool, the less the measuring times.

Highlights and difficulties of the activity:

1. Important: Measure with tools according to the correct steps. 2. Difficulties: (1) Understanding different distances and using the same tool to measure, the times are getting farther and farther, and the times are getting closer and closer. (2) For the same distance, using different tools, the number of measurements is different. The longer the tool, the less the number of measurements. Activity preparation:

Pencils, tables, road maps, watercolor pen sets, short watercolor pens and uncut pencils.

Activity flow:

Story guide: Today, the animal school will hold a grand sports meeting. Rabbits, bears and kittens all signed up for the competition. You see, the little animals will leave home for school soon. What kind of small animals will arrive at the gym first?

Second, learn to compare the distance of routes by means of tool measurement.

1. (Guide children to observe the road map) Let children observe and compare. What kind of animal is the closest to the gym? What kind of small animal has the farthest way to the gym? how do you know Is this method accurate?

2. Teacher: The method of seeing with eyes is called visual inspection, but visual inspection is definitely more accurate. What other methods can be used to judge the distance of the route? Let the children talk about their own ideas, such as tools: ruler, stick, rope, building blocks, etc. The teacher also brought a measuring tool to the children today. What tools did you bring? Teacher: Do you think this tool can measure the distance between a small animal's home and school? Let's measure how many watercolor pen covers the kitten needs from home to school. Can you measure them? Yes, please have a try.

Teach the measurement method in the process of children's trying, and guide the children to say the correct steps of measurement together while demonstrating (find the starting point, follow the line, and then measure) and record the measurement results in the table (the kitten measured five watercolor pen sets at school) 4. Teacher: Please also measure how many watercolor pens and caps the kitten uses at school. And record the results in the form.

Children's operation, teachers' tour guidance.

Please measure the number of watercolor pens of the other two small animals used in school and record the results in the table.

5. Ask the child to sit down and check the child's measurement results. The teacher summed up different distances and measured them with the same tool. The more times you measure, the farther you measure and the closer you measure. 6. Teacher: Teacher Zheng has also prepared two measuring tools for you. We will use these two tools to measure whether our small chair is good or not.

Ask children to demonstrate the measurement method and correct the wrong measurement steps in time.

7. Ask the child to sit down and check the child's measurement results. Teachers sum up the same distance, and the number measured with different tools is different. The longer the tool, the less the number of measurements.

Third, the teacher concluded that there are still many things in life that can be used as measuring tools. There are many in our classroom. Later, please choose what you like as a measuring tool to measure our desks and blackboards and compare the height of children.
