BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tray for placing an object to be counted as a learning tool for arithmetic, which is used for learning addition and subtraction by synthesizing and decomposing numbers.

[0002]

2. Description of the Related Art When a lower grade elementary school student learns a number, first, it is necessary to visually observe a concrete object, count the object, associate the concrete object with the number, and introduce it into learning of addition and subtraction. Is commonly done. For that purpose, give a child a number of objects, such as a hajiki and a block, as a counting object, and count any number of these counting objects in a tray, or move the arranged counting objects and actually try to synthesize and disassemble the numbers. Thus, a method of learning addition and subtraction is effective.

Here, the tray used heretofore has not been provided with an adhesive member such as a magnet.

[0004]

However, when a tray to which the above-described adhesive member such as a magnet is not used is used, the counting objects arranged on the tray are slid on the tray or discharged from the tray. When the counting object is used, the tray may have a frictional force generated between the counting object and the tray, or a magnetic force generated between the counting object and the tray when a magnet-containing object is used. It moves with the movement. Therefore, the child had to hold down the tray with one hand to prevent the tray from moving.

[0005] In a school or the like, when a child comes out and presents while showing his own tray, he or she must hold the tray with one hand and move the counting object with the other hand. Was inconvenient.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and an object of the present invention is to provide an easy-to-use counting object mounting tray suitable for arithmetic learning.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a method for counting and counting a plurality of counting objects such as repellents and blocks, and arranging these counting objects when learning addition and the like. A tray used for moving, wherein one side edge of an outer periphery of a base portion for arranging and placing the counting objects is for sliding the counting objects from the base portion and discharging the counting objects to the outside of the base portion. A peripheral portion for preventing the counting object from falling down from the base portion is formed on the other outer peripheral edge, and an adhesive member is provided on the back side of the counting object mounting surface of the base portion. Is attached.

According to the present invention, the objects to be counted can be arranged on the tray without falling down from the base portion, and the objects to be counted can be slid. Further, when the counting object is slid from the tray, the tray does not move with the movement of the counting object.

In the above configuration, when a magnet is used as the adhesive member, the tray can be attached to a learning iron plate or a steel blackboard by magnetic force.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a tray (hereinafter simply referred to as a “tray”) 1 for placing an object to be counted according to an embodiment of the present invention. FIG. 1 (a) is a plan view, and FIG. It is a bottom view and the figure (c) sectional drawing.

The tray 1 according to the present embodiment has a base portion 10 for placing the objects to be counted side by side, a discharge portion 20 provided on the base portion 10, and a peripheral wall portion formed on the base portion 10. 30 and a magnet 40 attached to the base 10. Hereinafter, each component will be described. In the present embodiment, an example will be described in which a magnet 40 is used as an adhesive member and a block containing magnets is used as an object to be counted.

The tray 1 is integrally formed of, for example, a synthetic resin or the like, and a thin plate of a magnetic material (for example, an iron plate) is formed thereon.
Is placed.

The base section 10 is for placing blocks side by side. Squares (here, squares of 2 rows and 5 columns) are formed on the surface (the surface on which the blocks are placed) 101 of the base portion 10 so that children can easily check the number of blocks. Have been. Also, the base 10
It is preferable to prepare various sizes according to the number of blocks arranged. For example, one row 10 shown in FIG.
There can be various variations, such as those with columns, those with one row and five columns shown in FIG.

The discharge section 20 is for sliding the block from the base section 10 and discharging the block outside the base section 10. When a plurality of trays 1 are used, when the plurality of trays 1 are used, when the plurality of trays 1 are combined with each other, the base portions 10 are located on the same plane, and The block is smoothly slid to the other tray 1.

The peripheral wall portion 30 is for preventing the block from falling from the base portion 10. The peripheral wall portion 30 is formed on a side edge of the outer peripheral edge of the base portion 10 excluding the discharge portion 20 so as to protrude toward the surface 101 of the base portion 10.

The magnet 40 is attached to the back surface 102 of the base portion 10 so that the tray 1 can be used by attaching it to a learning iron plate B (see FIG. 4). The magnet 40 is preferably a sheet-like magnet. In the present embodiment, the sheet-like magnet 40 is attached to two or three places.

Next, the tray 1 for placing the object to be counted having the above configuration.
Will be described with reference to FIGS. 4 to 6. FIG.

When calculating "6 + 3", a tray 1a in which six blocks A are arranged and a tray 1b in which three blocks A are arranged are placed on a learning iron plate B as shown in FIG. Then, the discharge sections 20 of each other are matched.

Next, when the three blocks A are slid from the tray 1b to the tray 1a, nine blocks A, six and three, are placed on the base 10 of the tray 1a. At first glance, the answer of 6 + 3 is 9
It can be understood that

Here, the tray 1a and the tray 1b have their base portions 10 located on the same plane, so that the child can smoothly slide the block A with one finger of one hand. In addition, each tray 1
Since the magnets 40a and 1b are placed on the learning iron plate B, the magnet 40 attached to the trays 1a and 1b sticks to the learning iron plate B.
a, 1b does not move unexpectedly.

When calculating "9-3", three blocks A are discharged from the discharge portion 20 of the tray 1 in which nine blocks A are arranged as shown in FIG. . Since the number of blocks A remaining on the tray 1 becomes six, the child can understand that the answer to 9-3 is six.

Using the tray 1 having the shape shown in FIG.
When calculating “−4”, four blocks A are discharged from the discharge unit 20 of the tray 1 in which ten blocks A are arranged as shown in FIG. Since the number of blocks A remaining on the tray 1 becomes six, the child can understand that the answer to 10-4 is six.

Also in the case shown in FIGS. 5 and 6, the tray 1 is placed on the learning iron plate B, so that the tray 1 does not move unexpectedly as in the case of FIG.

The tray 1 is placed on the iron plate B for learning.
However, the present invention is not limited to this, and may be, for example, a steel blackboard. Even when placed on a steel chalkboard, the tray 1 is stuck to the steel chalkboard due to the magnetic force of the magnet 40, and the blocks are also stuck to the tray 1 so that they do not fall off. By sliding the block on the tray 1 with one hand, it is possible to easily present the above calculation process.

As described above, the embodiment of the tray 1 according to the present invention has been described by taking the case where the magnet 40 is used as an adhesive member as an example. However, the adhesive member is not limited to a magnet, and may be, for example, a synthetic resin or an adhesive. A material having a high anti-slip effect, such as a rubber material, may be used. Also, the case where the block is used as the counting object has been described as an example. However, the present invention is not limited to this, and the present invention can be used even when a magnet-containing armpit, a piece, or the like is used as the counting object.

[0027]

As described above, according to the present invention,
One side edge of the outer periphery of the base portion on which the counting objects are arranged and placed is a discharging portion for sliding the counting object from the base portion and discharging the counting object to the outside of the base portion. The peripheral wall part that prevents falling from the part is formed, and the adhesive member is attached to the back side of the counting object mounting surface of the base part, so that the counting object does not fall from the base part. When the plurality of trays are used to connect the trays, the counting object can be slid from one tray to the other tray.

Accordingly, when the counting objects arranged on the tray are discharged from the tray, or when the counting objects arranged on a plurality of trays are slid from one tray to the other tray, the tray is moved. Since the tray does not move without pressing, the child can easily move the counting object with only one hand.

When a magnet is used as the adhesive member, the tray can be attached to a learning iron plate, a steel blackboard, or the like by magnetic force, so that the child comes out to show his or her tray at school or the like. When making a presentation, the tray can be attached to a steel blackboard and the counting object can be moved with one hand to explain the synthesis and decomposition of numbers.
