Abstract

The invention relates to computer technology and can be used to teach computing skills. SUMMARY OF THE INVENTION: the device consists of a housing, a pointer, rigidly mounted on a rotary axis, on which a profile cam is rigidly mounted, in contact with a roller mounted on the axis. The axis is fixed in an arm rigidly connected to the pusher fixed in the cylinder with the possibility of vertical movement of the pusher. The cylinder is rigidly fixed to the housing. A holder is rigidly fixed to the bracket, which serves to fit adjacent rods with scales applied to them. Slots are made in the doll-shaped housing, into which, when the cam is rotated, digital information printed on the rods is visible. 6 ill.

Description

The invention relates to computing vi can be used to teach children computing skills.

The purpose of the invention is to simplify the design and expand operational performance.

In FIG. 1 is a front view of a device for teaching computing skills; in FIG. 2 is a section AA in FIG. 1; on Fig, 3 is a graph of the dependence of the stroke of the push from the angle of rotation of the cam; in FIG. 4-6 - interchangeable rods with scales applied to them.

The device consists of a housing 1, which can be made in the form of a doll, a car, a house, etc., a pointer 2, rigidly mounted on the rotary axis 3. A profile cam 4 is fixedly mounted on the axis 3 and is in contact with the roller 5 mounted on the axis 6. The axis 6 is fixed in the bracket 7, rigidly connected to the pusher 8, mounted in the cylinder 9, with the possibility of vertical movement of the pusher. The cylinder 9, in turn, is rigidly fixed to the housing 1. On the bracket 7, the holder of the rods 10 is rigidly fixed to accommodate the interchangeable rods 11 with the scales applied thereon. A digital scale 12 is applied to the housing 1 and a hole 13 is made.

The device is mainly intended for learning and quick memorization of multiplication tables by children. Currently, the study of the multiplication table is carried out by the cramming method, as a result of which many students do not know the multiplication table even as high school students. Studying the multiplication table using the proposed device allows children to study the multiplication table during the game.

Thus, the proposed device combines two qualities: toys; study guides

The operation of the device is based on the fact that the cam profile is profiled according to a linear law, where H is the pushrod stroke and p is the angle of rotation of the cam.

where x is the distance in mm corresponding to the selected angle of rotation of the cam. - the scale of the angle of rotation of the cam.

Based on the above graph, you can build a cam profile and select interchangeable scales on the bar to implement the entire multiplication table. For example, if you need to multiply the number 2 by numbers from 1 to 10, then the scale can be added to the bar with the corresponding divisions. If you need to multiply by 3 then the rod will look as follows.

For the sake of clarity, at the free end of the rod, a number can be plotted by multiplication. For example, if we multiply by 4, then the scale on the bar looks as follows.

Operation with the device is as follows. When the pointer 2 is aligned with one of the numbers on the scale 12 printed on the housing in the slot 13 made in the housing, a corresponding answer appears depending on which rod 11 is inserted into the holder. Thus, the student, playing with the corresponding toy, simultaneously multiplies and learns the multiplication table, which contributes to the fastest memorization of the multiplication table during the game.

For example, if it is necessary to multiply the number 2 by the numbers from 1 to 10, then the rod 11 is inserted into the holder 10 with a scale printed on it, at the top of which the number 2 is applied. Then we rotate the pointer 2 so that its tip coincides with the numbers 1 , 2,3, 4, 5. 6, 7, 8, 9, TO of the digital scale 12 applied to the housing 1. In this case, the profile cam 4 rotates around the axis 3 and lifts the rod 8 in contact with the roller 5, as well as rigidly the holder 10 connected with it, together with the rod 11 inserted into it. When lifting the rod 11 in the slot 13, they appear. digits corresponding to the product of the number 2 by the number of the digital scale 12, against which the tip of pointer 2 is set.

Multiplication can be made and arbitrary numbers ranging from 1 to 10 friend

to a friend. For example, if it is necessary to multiply the number 5 by 9, then the rod 11 is inserted into the holder 10 with a scale printed on it, at the top of which the number 5 is marked.

let's make a point opposite the number 9 on the scale 12. In slot 13, the answer 9x5 45 appears. Multiplication of other numbers is done in the same way.
