Cell multiplication magnetic building block toy

Technical Field

The utility model relates to the field of children intelligence-benefiting toys, in particular to a latticed multiplication magnetic building block toy.

Background

The existing multiplication toy is generally multiplied by two numbers within ten, the number can be directly calculated, and the multiplication toy is not strong in interest and not large in challenge for children over 8 years old. Children over 8 years old often cannot operate through toy games to perceive multiplication of multiple digits by multiple digits. For this reason, we propose a grid multiplication magnetic building block toy, which can not only calculate multiplication of two numbers within 10, but also can calculate multiplication of a multi-number and a multi-number. The learning interest of the children is stimulated, and meanwhile, the ability of finding the rules and solving the problems of the children is cultivated.

In order to solve the technical problems, the utility model provides the following technical scheme: a grid multiplication magnetic building block toy comprises a building block bottom plate, a square magnetic building block with a left diagonal, a square magnetic building block and magnetic numbers (0 to 9).

On the basis of the scheme, the building block bottom plate is provided with a plurality of rows of convex solid small cylinders, the square magnetic building blocks with left diagonal lines and the front surfaces of the square magnetic building blocks are provided with magnets, and the back surfaces of the square magnetic building blocks are provided with 2-by-2 concave hollow small cylinders.

On the basis of the scheme, the square magnetic building blocks with the left diagonal lines and the square magnetic building blocks can be inserted into the building block bottom plate, and magnetic force numbers can be adsorbed on the square magnetic building blocks with the left diagonal lines and the square magnetic building blocks.

On the basis of the scheme, the square magnetic building blocks with the left diagonal lines are the same as the square magnetic building blocks in size, the length and the width of the magnetic numbers are smaller than the side length of the square building blocks, and the surfaces of the modules in the scheme can be set with different colors.

On the basis of the scheme, the square magnetic force building blocks with the left diagonal lines are spliced to form a grid graph required by grid multiplication.

Compared with the prior art, the utility model has the beneficial effects that: a latticed multiplication magnetic building block adopts a new structure, multiplication latticed graphs are pieced and arranged on a building block bottom plate, so that children can think what latticed graphs should be arranged in the game process, and the calculation requirement is met. By means of the number arrangement, addition and multiplication calculation are mastered, and the calculation capability and the problem solving capability of finding rules of children are improved. Meanwhile, a plurality of children can cooperate or compete to develop games, the learning interest of the children is stimulated, and the cooperation and social interaction capacity of the children is developed.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clear and concise, the lattice multiplication magnetic building block toy will be described in detail with reference to the accompanying drawings and examples. It should be specifically noted that the following specific examples are merely illustrative of the present invention and are not intended to limit the present invention.

In the description of the present invention, it is to be understood that the mathematical term is "lattice multiplication", which is a method of calculating the multiplication of two numbers introduced in the book "abstract of mathematical, geometric and proportional properties" by the italian mathematic scientist prochire in the middle of the 15 th century. The lattice algorithm is intermediate between the drawn line and the formula. The lattice multiplication is introduced in the four-grade mathematics upper book 48 pages of the human religious primary school.

Referring to fig. 1 and 2, it can be seen that: a grid multiplication magnetic building block toy comprises a building block bottom plate 1, a square magnetic building block 2, a square magnetic building block 3 with a left diagonal line and magnetic numbers 4.

The building block bottom plate 1 can be square or rectangular, a row of convex solid small cylinders 101 with the same row spacing is arranged on the building block bottom plate, and the more the number of rows and columns are arranged, the larger the number of factor digits can be calculated.

The square magnetic building blocks 3 with the left diagonal have magnetic force on the front surface and 2 x 2 concave hollow small cylinders on the back surface, the distance is the same as that of the convex solid small cylinders 101 in the bottom plate 1, and the corresponding grid patterns are spliced in the building block bottom plate 1 by the square magnetic building blocks 3 with the left diagonal according to the product of the digits of two factors in multiplication.

The front surface of the square magnetic building block 2 is provided with magnetic force, the back surface is provided with 2 x 2 hollow small cylinders which are concave, the distance between the small cylinders is the same as that of the convex solid small cylinder 101 in the bottom plate 1, and the square magnetic building block is spliced on the upper surface, the lower surface, the left surface, the right surface and the upper left surface of the grid graph in the building block bottom plate 1 respectively.

Referring to example fig. 1, to calculate 46 x 75, 2 x 2 diagonal square magnetic blocks are first assembled to the base plate 1 to form a 2 x 2 grid pattern. Respectively attaching magnetic force numbers corresponding to the factors to square magnetic force building blocks on the upper surface and the right surface of the grid graph, then calculating 6 x 7=42, attaching to the grid on the upper right corner, attaching 4 to the upper left side, writing 2 to the lower right side, and so on to fill the grids; finally, the numbers on the same oblique line are added, and the calculation is started from the lower right corner: 0; 2+3+0= 5; 4+8+2=14, one bit forward, 4; 2+1=3, and the

magnetic numbers

0, 5, 4, and 3 are respectively attached to the corresponding square magnetic blocks, thereby obtaining: 46 × 75= 3450.

Since the multiplication of two numbers has flexibility in the digits of the two factors, the corresponding trellis diagram changes as the digits of the factors change. The user can change the difficulty of the lattice multiplication by changing the factors and can set the factors according to a certain rule, thereby finding the rule and solving the problem.

The above-mentioned embodiments are merely exemplary embodiments of the present invention, and are not intended to limit the scope of the present invention, and any modifications, substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
