Description

The invention relates to advanced tutorials for learning to count, using boards with numbers moving in its slot. In the proposed tutorial, in order to get a better indication of the number, depending on its size, the bottom of the groove of the board has a color, the intensity of which gradually increases, and the numbers are made transparent or cut into the plates inserted into the groove. The manual consists of three pivotally connected boards, one of which, fitted with shelves, serves for laying objects, the number of which corresponds to the numbers depicted on the other two boards, intended for studying the metric system and the decisive number system.

In FIG. 1 shows the front view of the tool, all tr1 boards are located in one plane; FIG. Fig. 2 shows the arrangements (g Parts of the pillbox (in a side view) when it is used; Fig. 3-pivotal plates and Fig. 4- a set of pivotal plates with numbers.

The proposed in-depth tutorial is made of three articulated boards /, //, ///, divided into: the entire length by vertical lines. The board / is intended for studying the decimal number system, the board // - of the Metric system, and the board ///, equipped with partitions J4 with shelves /,

(256)

For stacking counting items. The end boards / and /// are provided for convenient folding when fastened with clasps. When used, the board /// is located on the table 3 (Fig. 2) ,. and boards I and II hang vertically up front to the sides. The board G has a recessed slotted 4 (FIG. 2), open on both sides, a groove 5 with different colors of the same color with the bottom 6, which is used for pushing and moving individual plates with stencil transparent or cut out numbers 7. On the board / is stationary, a clearly distinguished mark of the comma 8 which is slightly inserted from the top into the groove 6, Below is the free part of the board / for writing numbers with chalk.

The upper edge of the groove has on it the inscriptions of places, bits and classes of numbers (Fig. 1). The edges of the boards / and Ш are made in the form of a curve or broken line 2 to create an impression about the continuation of a numerical series.

The board L is provided with a cash table 70 and a table 7 / metric measures above and has a slot in the form of a pocket 72 for inserting J3 inserts (Fig. 3, 4) on top with the required name of the basic unit of metric measures. One of these inserts (meter) is depicted nested in FIG. 1, others

“Rai -nHTp and grams are shown separately“ and FIG. 3 and 4, and those parts of them which, when inserting inserts into "place, are invisible to the spectators, are shaded: are xx, and the parts opened by the slot have the required measure on themselves" and complement the names of bits that are characteristic of the metric system, available on the table. This gives us complex names for the measures: for example, the table contains an inscription den, and the liner 13 adds to the bottom a meter, a decimeter is obtained, and so on. Entire simple units are printed in capital letters: METER, GRAMM,, LITER, occupying both rulers (on the table in this place is a full slot).

In a separate box there are inserts 13, plates with numbers, matches, la-opox, and so forth, and with them ties or rezivnovy rings and bridges on Yu, 100 and 1000 peas, and also plates with metric measures of various kinds of hiring of 10 pieces. . each.

The manual is used as follows. The /// board is laid horizontally on table 3, while the other two boards hang from its edge to the floor "vertically towards the viewer of fig. 2). Then take an arbitrary number of homogeneous objects (for example, matches), KOTOpbie is required to be counted, and {break into tens, tying each into a bundle. The remaining units (less than 10) are placed on the subject shelf above the unit name, to the left of the full value. The obtained tens are counted and connected by 30 pieces. together, held together in the hundreds. The remaining (less than 10) desks are placed in the second row on the shelf, etc. If there is no residue, the row remains empty. Each time,.-Fill the row on the shelf, slide the plate into the groove at the appropriate place, “a digit of which means the number of units and a number of units. Due to the transparency of the numeral and the difference in the color of the bottom of the 6th groove, the figure is higher (the size is darker and gives the impression of greater significance than the discharge and class. The zeroes fill L1 empty places under empty rows. Teach you to dial any numbers ia shelf, and teaches you to fill in the groove or vice versa: put figures in the groove before, and then on the shelf.

as well as moving numbers along the slot to the right and to the left and observe the position of the comma and make the necessary permutations: Cha subject shelf. Still & The commandingly shows that it can only move by number along with the entire instrument, with all its three parts, in other words, it is immovable on the table, but, on the contrary, the number moves along the table.

Hetpyd, having examined the table of measures on the board //, understand its application and close communication with the corrosive / and object shelf (board ///), which will already be filled with metric measures, if possible, with natural, or their images.

The proposed manual can also serve to explain any numbering system, not only a decimal one, but also, for example. hexadecimal, octal, etc. — it is only necessary to replace the names of bits and classes with exponents.

In order to avoid scattering the attention of students, flaps in the form of plates can be used, hanging by loops on hooks hammered in the appropriate places of the boards. Similar shutters, closing, as necessary, these or other categories of benefits, give the opportunity to learn more; intensive study of a single department.

The subject of the patent.
