2. Then, take out the plane figure and put it on the paper. Parents can ask their children to count how many triangles, squares and circles there are and ask them questions. There are fewer circles than triangles.
3. Take out solid geometry, let the children identify cubes, cuboids, spheres, cylinders and cones, and let the children count the number of geometries, as shown in the figure below.
Take out the stick in the box. Parents can ask their children to do simple addition and subtraction. As shown in the figure below, they can count with sticks or output mathematical addition and subtraction.
Parents can tell their children the abacus on the school box and let them know that the numbers come from the right and the ten digits are on the left. The beads above can be dialed, and the clock next to it can be used to learn time, as shown in the figure below.
6. After learning the learning box, parents should tell their children to tidy up the learning box and put their own teaching parts in it. This can also be organized. Through the use, children's mathematical ability will be improved after a period of time.
