? Students, when the summer vacation comes, we should keep in mind safety, continue to study, stay healthy and work every day. I hope you can arrange your time scientifically and reasonably and have a safe, full, happy and meaningful holiday! The special assignments for this summer vacation are as follows:

1. Practice 20 math problems every day. (Fractional addition, subtraction, oral calculation, fractional mixing operation, solving equations, circumference and area of a circle. The above three ways, two ways to solve the problem).

2. Record the maximum and minimum temperature of each day in a week during the holiday, and draw a composite broken-line statistical chart.

3. Make three mathematical tabloids: all the learned "unit conversion", "perimeter of plane figure" and "area of plane figure" should be illustrated.

4. Make 1 summer vacation safety manuscript.

5. Find the cuboids or cubes in life, measure their length, width, height or side length, and record them in tabular form.

6. Stick to skipping rope for 5 minutes every day.

7. Do whatever housework you can every day.
