Description

[Detailed explanation of the invention] This invention relates to a math teaching toy that is used by students in the lower grades of elementary school, such as the first grade, as a teaching material for mathematics. To provide an arithmetic teaching material toy with a novel structure that does not exist in the past, which allows students of the same grade to understand numbers.

Hereinafter, one embodiment of this invention will be described with reference to the drawings. In the drawing, 1 is an oblong-shaped stand body integrally molded from plastic, and a piece sliding receiving part 2 is provided at one end in the length direction (the right end in the figure). , and a base plate support portion 3 that is gently inclined downward to the right (for example, at a slope of about 1/40) toward the falling piece receiving portion 2 is formed by the inwardly protruding flange edge of the frame edge portion 4. Reference numeral 5 denotes a vibrating base plate installed on the base plate support part 3 of the base body 1, which vibrates back and forth in the direction of the piece sliding receiving part 2 within the frame edge 4, and there are three vibrating base plates in the middle part in the longitudinal direction. Piece repelling protrusions 6a, 6b, and 6c protrude in the arrangement shown in the figure. Reference numeral 7 denotes a base plate actuating mechanism that vibrates the base plate 5 back and forth in the direction of the piece sliding receiving part 2 with a constant stroke (for example, a stroke of about 5 mm). Ratchet foil 1 installed coaxially with the knob wheel
0, a base plate backing moving plate 11 with protruding pieces repelling protrusions 6a to 6c, and a rotating lever 14 whose intermediate portion is pivoted to the main body bridging rib plate 13 by a pin 12.
and a protruding pin 15 provided at one end of the lever is engaged with the ratchet wheel 10,
Also, a protruding pin 1 provided at the other end of the lever 14
6 into the center hole of the protrusion 6a of the base plate backing moving plate 11 as shown in FIG. It is strong. A plurality of pieces 18 are placed on the starting part 5a of the vibrating base plate 5 and are slid on the base plate surface by the vibration of the base plate 5 to be moved to the piece sliding receiving part 2. For example, 20 pieces are prepared so that they can be placed in two rows of 10 pieces each. 19 is the stand body 1
A movable small box for storing pieces is installed in the piece sliding receiving part 2, and a game can be played to see how many pieces 18 can fit into this small box.

Then, for example, ten pieces 18 are arranged in parallel on the starting part 5a of the base plate 5, and the rotary knob 9 is set to the first position.
When manually rotated in the direction of the arrow in FIG. Piece spring return protrusions 6a to 6c in the middle
Pieces 18 that hit the projections 6a to 6c are bounced back in the direction of the starting part 5a, etc., and the pieces 18 that pass through that position without hitting the protrusions 6a to 6c advance in the direction of the sliding receiving part 2 and fall into or into the small box 19. It comes to be slid down and stored in the sliding receiving part 2 which has come off.

Therefore, if we separately count the pieces 18 that entered the small box 19 and the pieces 18 that entered the small box out position of the sliding receiving part 2, there is a force that divides the number into two (for example, 10 is 3 and 7, etc.) You can develop the ability to compare numbers, and the ability to match numbers.

Incidentally, even without the small box 19, such a force can reduce the number of pieces 18 that have slipped into the piece-sliding receiving part 2 and the number of pieces 18 that remain on the base plate 5 even if the small box 19 is not present. It can also be learned by counting.

Since the arithmetic teaching toy of this invention is as described above, it has the educational effect of allowing lower grade students to understand numbers by having multiple pieces compete on a vibrating base plate. .

Claims (1)

[Scope of utility model registration request] A stand body is provided with a piece sliding receiving part at one end in the length direction and a base plate supporting part that is gently inclined in the direction of the piece sliding receiving part, and a board is installed on the bed plate supporting part of this stand main body. The vibrating base plate has a plurality of piece repelling protrusions protruding from the longitudinally intermediate portion thereof, and the base plate is moved in the direction of the piece sliding receiving part by manually rotating a rotary knob provided on the operating section of the base body. The machine includes a baseplate operating mechanism that vibrates back and forth with a constant stroke, and a plurality of pieces that are placed on the start part of the baseplate and are slid on the baseplate surface by the vibration of the baseplate and are moved to a piece sliding receiving part.
