In addition to the two circles, the ruler has a rectangular slot for a small gear wheel with which you can draw rectangular patterns. Also, the entire ruler along the perimeter also has teeth, which makes it possible to draw all kinds of openwork frames.
If the child is 3-4 years old, then in order to quickly adapt and strengthen the hand, you need to start drawing from the central holes of the wheels. And then in a spiral: from the middle to the edge of the gear wheels.
gradually the child develops coordination of hand movements and hand motor skills. Remembers which figure draws what. And in a day or two he will learn what patterns each hole makes on any wheel or figure. Now you can start combining with colored pens. We begin to simulate warm tones (red, yellow, green) with cold ones (blue, cyan, violet). A little more time and harmonious patterns will appear, and you and your child will master the secret of color.
This is where the time comes to obtain spatial drawings. By painting the near or distant background on the pattern, three-dimensional drawings are created. By superimposing a pattern one on top of another and a pattern on a pattern, entire panoramas of colors are obtained. And you plunge further and further into your own fantasy world...
The spirograph was invented by British engineer Denys Fisher (1918-2002) in 1962. The invention did not help Denis advance in his work, but his family members liked it so much that he decided to release it as a toy. The first customers received the toy in 1965.
The Spirograph was named the world's best educational toy for 4 years in a row, from 1965 to 1969.
A standard spirograph is a rectangular ruler (main stencil) with two working serrated holes inside. The holes are round in shape and have different diameters. There are 96 cloves cut in the smaller hole and 105 cloves in the larger hole.
The ruler comes with several gears with holes inside, and a set of figured stencils that have the correct geometric shape (rhombus, triangle, square, star, octahedron).
The complete set also includes stencils in the form of fish figures (dolphin, shark), butterflies, bow, hedgehog, cat, crosses and a protractor stencil in the form of a circle.
Spirograph is one of the most highly intellectual games of the 20th century. The number of patterns drawn is calculated as a number followed by four zeros. And it is limited only by the imagination and abilities of the person himself.
In children, the spirograph develops imagination, fantasy, creative and logical thinking, drawing ability, hand motor skills and hand coordination. Improves handwriting character and increases writing speed. Teaches color modeling and spatial thinking. Improves aesthetic abilities and increases intelligence.
In adults, the spirograph increases vitality and calms nervous system. As a result, the amount of stress and minor illnesses decreases. Can be used for various types of design and drawing work.
Spirograph is a new type of game that simulates the creative process itself and creates its own microclimate. Physiologist X. Hoagland, drawing attention to the depth and complexity of intellectual creative games, said, "Understanding the atom is child's play compared to understanding child's play."
A little math
Hypotrochoid with parameters R= 1.0, r= 0.6, d= 1.2.
A figure obtained using a simple spirograph from two circles, when a small one (of radius r) with a hole at a distance d from the center rotates in a large one (of radius R), is called a hypotrochoid. Its formula in Cartesian coordinates:
The patterns obtained using a spirograph directly depend on the number of teeth on the working circles and movable wheels.
The patterns drawn with squares, stars, butterflies, etc. depend on the distance between the teeth of these figures. This is where the concept of “squaring the circle” comes into force.
The entire length (along the perimeter) between the teeth of the figure can be expressed in terms of the circumference. For example, drawing with a square and a circle, whose perimeter is equal to the length of the circle, will result in patterns with an equal number of points. Only a pattern drawn in a circle will have rounded points (rays), while a pattern drawn in a square will have broken, sharp points.
You decided to draw
A line with a set of figures must be of high quality - that is, from a good manufacturer. Otherwise, you risk wasting a lot of energy and nerve cells. The spirograph is a fairly high-precision instrument. The resulting pattern and, of course, your mood directly depend on the accuracy of making its teeth and figures.
And so, you have in your hands a good spirograph with a set of figures. Where to start? First of all, you need to stock up on a set of pens or pencils. Better than pens. Felt-tip pens are not suitable, as they will smear the design on the paper under the wheels of the spirograph. It is advisable to take thicker paper, but you can draw on a regular photocopier.
Put album sheet on a flat table surface. Make sure that no small objects, grains of sand, or crumbs get under the sheet, otherwise they will all appear on the paper after drawing. Then place the Spirograph with the smooth side on a piece of paper.
Place a wheel or figurine into the working toothed hole so that its teeth engage with the teeth of the working hole. Insert the handle into one of the holes in the wheel or figurine and slowly roll it along the jagged circle. At the same time, lightly press the main stencil onto the paper. The pen will begin to draw a pattern. After a few turns around the working circle, the handle will return to its original point and the pattern will close.
Change the color of the ballpoint pen and the hole and repeat the circular movements with the wheel or figurine again, just like the first time. We got a different pattern on top.
It must be said that if you are drawing with a spirograph for the first time, then make all circular movements along the working circle smoothly, slowly, without lifting the wheel or figure from the teeth of the spirograph. It's like riding a bike for the first time. You need to put in some patience and effort to ride it. It’s the same here: ten minutes of training, and you’re quickly turning the wheels with the handle along the teeth of the working circle. And after half an hour - you are already aces in this matter.
If the child is 3-4 years old, then in order to quickly adapt and strengthen the hand, you need to start drawing from the central holes of the wheels. And then in a spiral: from the middle to the edge of the gear wheels.
Using figured stencils (squares, stars, fish, butterflies, etc.) is a little more difficult to work with, but also more interesting. The figures roll in jumps, through several teeth along the working circumference of the spirograph.
When a child begins to easily draw with butterflies, bows, squares, triangles, then skill appears and, of course, delight and joy. And when children master the technique of moving fish and a diamond along a jagged circle, then mastery and confidence in their creativity appear.
The spirograph ruler is an amazing and strange thing, something between a protractor. To the untrained eye, this toy appears to be a complex device designed for creating intricate design drawings. Indeed, the spirograph was made in 1962 specifically for working on drawings of aerial bombs. Denis Fisher's invention was not useful in the development of weapons, but the children were delighted. After the engineer registered a patent for the spirograph and put it on sale, this toy received recognition all over the world.
Equipment
A spirograph ruler consists directly of a main stencil and several jagged elements of regular geometric shape with holes inside. There are additional stencils in the form various figures(butterfly, cross, bow) and a ruler-protractor in the form of a circle. The resulting pattern depends on the number and distance between the teeth of the moving elements. Using different drawing methods using templates, you can get fancy openwork images.
How to draw with a spirograph?
In children, the spirograph ruler helps in the formation of creative and logical thinking, improves fine motor skills and develops hand coordination. In adults, when drawing, irritability decreases and stress resistance increases. A smart purchase for the whole family is a spirograph ruler. How to draw so that using this device in creativity is beneficial?
The landscape sheet should lie on a flat surface. The spirograph is placed with the embossed side up. The insert figurine is inserted inside the ruler so that the teeth connect to the working hole. Using a pen inserted into one of the holes in the insert, without lifting the figure from the teeth of the ruler, make smooth rotational movements. The pen will begin to draw spiral patterns. After a few turns in a circle, the pattern will close at the starting point. You can experiment with the design, changing the stencil holes and colors, and the shading of the resulting vignettes.
To strengthen the child’s hand coordination, you need to start drawing from the inner holes of the earbuds. Such drawings will be larger. It’s a little more difficult, but more interesting, to work with curly stencils. The figures move unevenly, irregularly around the working circumference of the spirograph.
Why use a spirograph?
Many children need training in hand movements before entering school. A stencil ruler will help you learn to write more accurately and quickly. Spirograph in game form For schoolchildren, the process of drawing soft symmetrical lines trains the muscles of the hand, this helps improve handwriting and increase the speed of writing. The spirograph ruler improves visual perception, the concept of spatial structure, and aesthetic image. This activity calms an adult. The geometry of Buddhist mandalas is similar in structure with precise proportions of patterns. Drawing rounded lines leads to harmony.
For children
Playing with a spirograph is a creative process. Among the advantages inherent in using this toy, one can note an increase in the child’s perseverance. Drawing with Spirograph figures is a fun activity. The number of patterns drawn is great. Their number is limited only by imagination. When a child moves away from template patterns and begins to draw easily using figures, then mastery and confidence in their skills appear. Step by step, from simple to complex, motor skills and hand coordination develop, and the relationship between the figures and the resulting patterns is memorized. Gradually, combining colors and lines, harmonious patterns appear. An educational toy improves a child’s artistic abilities and develops visual skills. The use of stencils can be used for creative works.
A mesmerizing effect - transforming chaotic lines into clear ones. The opportunity to create, to feel like a designer, will be given by a spirograph ruler. The price of this smart toy is a particularly attractive factor. Simple models of spirographs can be found on sale for about 14 rubles.
