1. Everyone should bring a white draft book. (Specific requirements: white, no grid or horizontal lines, preferably A4 paper size, at least 40 pages, with cover. ) This is to teach students to draft and form a good habit of drafting.
2. Everyone should prepare a set of triangle and protractor. Cultivate students' habit of standardizing painting.
3. Pencils and erasers. (Pencils buy 2B pencils).
4. You can't bring school supplies: math reference books, correction fluid, correction tape, correction paper, etc. (Not allowed at school and home) and calculator.
The fourth grade mathematics mainly studies the mixed operation of integers and primary schools, the characteristics of triangles, and the multiplication and division of multiple digits. The focus of fourth grade mathematics learning is parallelogram, trapezoid and statistics, which is the difficulty of the first volume of fourth grade mathematics in primary school. Understanding of large numbers, multiplication and division of two digits and understanding of angles are the key points.
Main learning contents of fourth grade mathematics:
1, understanding of numbers (understanding of numbers within 100 million, comparison of multi-digit sizes, expression of large numbers in tens of thousands and hundreds of millions, approximate numbers, positive and negative numbers).
2. Digital operation (two-digit multiplication, three-digit division, three-step mixed operation with brackets, counter).
3. Explore the laws (multiplication and exchange law, association law, distribution law, additive commutative law, association law, constant quotient law).
4, graphic understanding (line segments, rays, parallel lines, right angles, rounded corners) measurement. Measurement unit, draw angle with protractor, measure angle.
5, graphics and position (on the grid paper with several pairs of position, direction and distance to determine the position of the object).
6. Graphics and transformation (simple comprehensive transformation of simple graphics rotating 90 degrees and translational rotation).
7. Simple data statistics (1 grid represents bar statistics, simple statistics and broken statistics of multiple units).
