? Dear children:? Hello! A semester of intense study is over. We know that there is mathematics everywhere in our life, and we can't live without it everywhere. Let's have a happy and meaningful summer vacation! In order to make you gain more in the summer vacation, the teacher assigned the following summer homework. The contents of this summer's math homework are as follows:

First, oral arithmetic homework

? Do 10 oral calculation exercises every day, and do 5 vertical calculations within 100.

Second, preview homework.

Preview the math book in the first volume of the second day of junior high school.

Third, practical work.

1, little designers, do you still remember the three-dimensional graphics we learned? You must have these graphics at home: toothpaste box, ball, tea box, Rubik's cube. Let's use these figures to spell out a work of art we like and see whose hand is more skillful!

2. Mathematics in life

? This semester, we got to know RMB, and I believe the students have mastered RMB. Please write a shopping diary.

? Finally, I wish the children a happy holiday and healthy growth!
