Little Shoe Store PPT, Part 2: Introduction of New Knowledge

The students in the naughty class want to simulate opening a shoe store, and they need to investigate in order to "replenish goods".

Some shoes have been sold out, which is not enough, and some shoes have not been sold at all. What is going on?

During the purchase, the same quantity of shoes from sizes 32 to 40 was purchased. As a result, all the shoes in sizes 34 and 35 were sold out. This was not enough. However, one pair of shoes in sizes 39 and 40 was not sold. Why?

Tell me, how can I investigate?

Survey method analysis

Because the shoes worn by everyone have different shoe sizes, you can check the shoe sizes of your classmates. If the shoe size is larger, put more in it, and if the shoe size is smaller, put less. And because boys and girls are different, boys and girls can be investigated separately.

You can investigate the shoe sizes of your classmates and get more if you have more.

investigative methods

Method 1: Raising hands.

Each person can only choose one shoe size. Whenever a shoe size is mentioned, the students who are suitable for this shoe size will raise their hands respectively, boys and girls, and then record them.

Method 2: Asking method.

Ask each student's shoe size one by one and record it, boys and girls record it separately.
