Do 10 cross calculation problems every day, 5 calculation problems (written multiplication, division, elementary arithmetic and simple operation) and 3 problem solving.

? Collect the questions that you don't know well and don't master well enough, and make a set of examples, which is conducive to targeted learning in the future and guides students' learning methods.

Second, the inquiry homework

? 1. Make a simple scale (balance scale or hook scale). A simple scale can be made of plates and rubber bands. You can simply weigh an object, and every time you add an object (the same object), you can record the length of the rubber band. Explore the relationship between the length of rubber band and the number of objects, and make records, or take some moving photos.

Or an inquiry assignment to expand and extend the knowledge of this semester.

Third, hands-on operation.

1. Make learning tools: two identical triangles, two trapeziums, 1 parallelogram, 1 parallelogram. Parents can help draw it well, and students can cut it after observing the characteristics.

? 2.Run 1 illustrated mathematical handwritten newspaper or mathematical clippings, the contents of which can be mathematical stories, mathematicians' stories, interesting mathematical problems, mathematical knowledge introduction, mathematical riddles, mathematical famous sayings and mathematical ballads. The page size is 8.

? Objective: According to the learning content of this semester, design some practical topics and create some works for students.

Fourth, practical activities.

? 1. Flip a coin 50 times and record the number of heads and tails in the form of a table.
