Geometry, like any exact science, does not tolerate neglect. And to help learn its basics, children should do a little needlework quest. Its main theme will be the following: how to make a protractor. To do this, you need a little: scissors, glue, A4 paper, thick cardboard, pencils, felt-tip pens, paints, brushes, various décor, a printer, well, where without a ton of patience and a bag of inspiration! The need to complete such a task in front of the child can be argued by the absence of such an important angle meter in the store or stimulated by more familiar methods for you.
Preparatory Activities
The first thing that lies solely on your shoulders will be the preparation of the template. Currently, finding the right option is not difficult. If you own graphic editors, you can create a unique pattern with your family photo, names, characters of your favorite cartoons. But do not get carried away, because in this way you will get only a colored paper protractor - print it, and your joint leisure with the learning elements will be disrupted.
A much better solution will only be the preparation of a circuit with a digital scale, which will be colored and improved in every way. It is also worth deciding which protractor to print - round for ease of display, a semicircle with values from 0 to 180 degrees. If such simple methods are not for you, we immediately turn to the methods of presentation in rational trigonometry.
An excursion into history and a little about modernity
Before the final decision is made about which protractor to print, you can tell your child about the history of this instrument (it comes from ancient Babylon), familiarize yourself with the six - decimal system of calculus and its basic concepts - degree, minute, second.
It will not be out of place to touch upon the use of angles in modern society, in geodesy and cartography, construction, engineering, etc., to show the main types of angles - sharp, dull, straight, wide, and also to explain the difference between them. It is recommended that you independently display these angles in order to create drawings of certain things on their basis. While this will be done, check how to print the protractor: you need to make sure the quality of the template prepared in advance and its high resolution. The printer should also display data without distortion or distortion. You may need to clean it or set it up.
Creative process
After deciding on which protractor to print, you just click on the "Print" button (you can specify several copies), and then cut the part along the contour.
It is necessary to be careful, because any inaccuracies will be in sight. And then proceed to decorating the protractor. Anything will do for this, the option only depends on how much you are passionate about this business together.
All types of dyeing compounds, cotton threads and ribbons of various shades, wool, cotton wool, stickers, beads, rhinestones and bows will find their use, because in this case their excess will not be a disadvantage. After the end of the process, the artistic value of the protractor will increase at times, it can be glued to cardboard and make a hole in the mark where the measurements begin. Despite the fact that this self-made copy may be less convenient to use than its transparent factory-made counterparts, it will not leave anyone indifferent due to its cute appearance and original design. Similar events with your child will give you many pleasant minutes in the future.
