1, making geometric model.
Materials: cardboard, scissors, glue, ruler, triangular ruler, compasses, etc.
Steps: according to the geometric figures in the textbook, design the required geometric model, then draw the corresponding shape on the cardboard, cut it with scissors, and finally stick all the parts together. For example, to make a cube, you can cut six faces from the cardboard according to the graphics in the textbook and then stick them together to form a cube.
2. Make a counter.
Materials: a small board, some beads, a small stick, some ropes, etc.
Steps: Draw the scale of the counter on the small board, then thread the beads according to different digits, string the beads with a small stick, and finally fix the counter on the small board with a rope. For example, to make a decimal counter, you can draw ten cells on a small board, each cell represents a number, then put the beads on according to different numbers, string the beads with a small stick, and finally fix the counter on the small board with a rope.
3. Make windmills.
Materials: a piece of paper, a pair of scissors, glue or stapler, etc.
Steps: Fold a piece of paper into a square, then fold it into a triangle along the diagonal, fold the two corners of the triangle toward the center, then cut off the redundant parts with scissors, and finally fix the top and bottom of the windmill together with glue or stapler. For example, to make a windmill, you can fold a piece of paper into a square, then fold it into a triangle along the diagonal, fold the two corners of the triangle toward the center, cut off the redundant parts with scissors, and finally fix the top and bottom of the windmill together with glue or stapler.
The purpose of making mathematics learning tools:
1, which helps to understand abstract concepts.
Some concepts in junior high school mathematics are abstract, such as functions and triangles. These concepts need to be understood through concrete examples or intuitive ways. By making mathematics learning tools, abstract concepts can be concretized and students can better understand them. For example, making a geometric model can help students better understand the shape, size, angle and other characteristics of geometric figures, so as to better master geometric knowledge.
2. Improve math skills.
Making mathematical learning tools requires certain mathematical skills, such as measurement, calculation and drawing. By making math learning tools, students' math skills and abilities can be improved. For example, to make a counter, students need to master the decimal counting method, know the numerical value of each number, and at the same time need to make simple calculations and measurements.
3. Stimulate interest in learning.
Making mathematics learning tools can stimulate students' interest in learning mathematics. By making mathematics learning tools by hand, students can feel the interest and practicality of mathematics, so as to better devote themselves to mathematics learning. For example, making a windmill can make students feel the power and function of the wind, and at the same time, it can also make students feel the symmetry and proportion of mathematics, so as to better understand mathematical knowledge.
