Who is the tallest lets children experience the happiness of growing taller. On the basis of children's interest and knowledge in measurement, we should understand and operate end-to-end measurement methods, try to use a variety of measurement skills, explore new measurement methods and solve problems encountered in life.

Activity objectives:

1. Learn more about end-to-end measurement methods in free exploration and cultivate children's observation ability and operation ability.

2. Experience the different results measured by various measuring tools, be able to record them carefully and express the measurement results in correct language.

3. I like to take part in surveying activities, and I am willing to use what I have learned to solve problems I have encountered.
