Material preparation: pencils, rulers, cardboard, sticks, scissors, glue, etc.
1. First cut a polygon, draw it on a big cardboard, draw two polygons, and cut them off with a knife.
2. Cut another long watch strip, then enclose the polygon with a long cardboard strip and stick it with glue.
3. Find the center of the polygon and connect the vertices with a ruler and pencil. Found the center point. Then make a small hole in the middle.
4. Always make six such solid polygons according to the above method.
5. Paste two such small circles with cardboard, also find out the center point, and then punch holes in the center point.
6. String a small circle on it with a wooden stick, then string six polygons on it, and then install a small circle.
7. Finally, fill in the arithmetic problems you want to calculate according to the edges of the polygon, so that a toy that can be used for brains and fun will be done.
Introduction to mathematics manual:
Math handiwork is a kind of creative handiwork, which can help children learn math knowledge better. It can help children turn boring mathematics knowledge into more interesting learning methods and help them better understand and master mathematics. Mathematical handwork can use different materials, such as cardboard, colored paper, foam board, bamboo sticks, glass beads, magnets and so on. Through matching and puzzles.
For example, you can make a model of a thousand-layer cake to help children understand the different bit values of thousands, hundreds, tens and single digits; You can also make a counting clock to help children master time and counting knowledge; Or you can make 3D numbers with cardboard and colored paper to help children know and understand the spatial concept of numbers, as well as mathematical concepts and skills such as the decomposition and merger of numbers.
By making mathematical handcrafted products, children can gain mathematical knowledge in the fun of handcrafting, so as to understand and apply the learned mathematical knowledge more deeply and practically. At the same time, because mathematics manual operation needs children's manual operation, it can also help cultivate children's hand-eye coordination, creativity and thinking ability.
