1. Pencil: Pencil is one of the most basic writing tools, and 2B pencil is generally used to help students write and draw.

2. Eraser: Eraser is used to correct writing mistakes and facilitate students to erase incorrect handwriting.

3, pencil case: pencil case is used to store pencils, erasers, pens and other stationery, easy to carry and organize.

4. Ruler

A ruler is a tool for measuring length. The common length of a ruler is15cm or 30cm. In mathematics learning, a ruler can be used to measure the length of line segments to help students understand the relationship between values. When using a ruler, it is necessary to aim the starting point of the ruler at the measured object and read the scale on the ruler to get the accurate length.

5. Extensor

A protractor is a tool for measuring angles, which usually includes semi-circular and full-circular. In mathematics learning, protractor is often used to measure the size of angles and draw graphs with specific angles. When using the protractor, it is necessary to aim the center of the protractor at the vertex of the angle, and then read the scale value on the protractor to get the accurate angle.

6. Calculator

Calculator is a tool for numerical calculation and operation. In mathematics learning, calculators can help students perform basic operations such as addition, subtraction, multiplication and division, and solve some complicated calculation problems. When using the calculator, you need to input the numerical values and operation symbols correctly, press the corresponding function keys, and then read the calculation results.

The significance of mathematics

Mathematics is the study of quantity, structure, change, space and information. The quantitative relationship and spatial form described by mathematics naturally become the basis of physics, mechanics, astronomy, chemistry, biology and other natural sciences.
