Mathematics learning tools exist objectively, which can be observed, touched, perceived and used, and can help students learn mathematics knowledge. It usually includes mathematical models, images, charts, etc. Mathematics, mathematics, mathematics, commonly used sticks, counters, abacus, etc. Commonly used plane graphics are square, rectangle, circle, triangle, trapezoid and so on. Cubes, cuboids, cylinders and spheres are commonly used in three-dimensional graphics. In addition, there are rulers, triangular plates, nail plates and so on.

Mathematics learning tools are widely used in mathematics classroom, which can increase the intuition of teaching and cultivate students' hands-on operation ability. Especially the students in the middle and lower grades are in the critical period of the transition from thinking in images to thinking in abstract logic, and the use of mathematics learning tools is even more essential. This paper studies the effect of mathematics learning tools on students' learning mathematics knowledge and improving their ability from three aspects: number and algebra, graphics and geometry, and comprehensive practice class.
