Description

Coding teaching tool using polyomino {CODING　EDUCATION APPARATUS USING POLYOMINO}

The present invention relates to a coding teaching tool using polyomino, and more specifically, it can provide a puzzle learning effect while assembling a polyomino-type block part on a base plate, and recognizes the block part mounted on the base plate as a smart device for coding. It relates to a coding teaching tool using polyomino that can provide coding learning effect by playing a game by inputting a command.

Recently, as coding is included in the elementary curriculum, interest in coding education for children is increasing, and coding teaching aids with various forms and game methods are being released.

As an example of a technology for such a coding aid, Laid-Open Patent Publication No. 10-2017-0107611 discloses a command stick with a built-in unit command for the command, a base board on which the command stick is arranged, and a unit command transmitted from the command stick to the base board It includes a connection support unit including a board connection part provided on the base board and a stick connection part provided on the command stick to be connected to the board connection part, and a detachable support unit for enabling and fixing the command stick from the base board by magnetic force. A teaching aid for learning coding has been disclosed that the baseboard includes a command transmission unit that transmits unit commands to the actuator according to the arrangement order of the command sticks through wired or wireless communication.

On the other hand, in general, infants and children were able to improve fine muscle development and brain development through prefabricated teaching aids that can make various types of block sets by inserting several blocks into a wide block board.

As an example of such a technique for prefabricated teaching tools, Utility Model Registration No. 20-0291736 is a main block composed of a plate shape having a certain area and horizontally arranged, and a number of assembly protrusions protruding upward on the upper surface, as shown in FIG. 1 . The plate 5 and a plurality of basic blocks 7 that were assembled to the main block plate 5 were formed in the form of a plate 5 and a non-standardized brick shape, and a protrusion insertion groove to be fitted to the assembly protrusion was formed at the bottom. .

Here, the protrusion of the same shape as the assembly protrusion of the main block plate 5 was formed on the upper part of the basic block 7 to protrude upward, so that it could be assembled vertically between each basic block 7 as well. In addition, as in FIG. 1 , in addition to the basic block 7 , the launch pad 10 , the guide tube 11 , the switch box 12 , the search light 13 , the rotor 14 , the speaker 15 , and the control tower 17 ), a control box 18, a power supply box 19, and a vehicle 21 were further provided to provide various additional functions.

However, the conventional coding teaching aids and prefabricated teaching aids are each made of a configuration that can implement a unique educational purpose, so the conventional coding teaching aids can only provide coding learning, and the conventional prefabricated teaching aids can only provide assembly learning. In other words, there was a problem in that the financial burden was aggravated because it was necessary to purchase the coding teaching aids and the prefabricated teaching aids in order to perform coding learning and prefab learning at the same time.

In addition, the conventional coding teaching aids have a structure in which only a single game can be played in one teaching aid, so children can easily lose interest. There was a problem in that the human burden was further aggravated.

Publication No. 10-2017-0107611 (2017.09.26), a teaching aid for learning coding. Registered Utility Model Publication No. 20-0291736 (Sep. 30, 2002), Block toys to promote creativity.
