How to study the geometry and protractor print out?
Geometry, like any exact science, does not tolerate a disparaging attitude. And to help her learn the basics, children should conduct a small quest for needlework. Its main theme will be: how to make protractor. To do this, you need a little: scissors, glue, A4 paper, thick cardboard, pencils, markers, paints, brushes, various decor, printer, well, where without a ton of patience and a bag of inspiration! The need to perform such a task before the child can be argued by the absence of such an important corner meter in the store or stimulated by more familiar methods.
Preparatory activities
A much better solution will be to prepare a contour with a digital scale that will be painted and perfected in every way. Also it is necessary to decide what type of protractor to print - round for simplicity of display, semicircle with values from 0 to 180 degrees. If such simple methods are not for you, we immediately turn to the methods of representation in rational trigonometry.
An excursion into the history and a little about the present
Before you make a final decision on which protractor to print, you can tell your child about the history of this tool (he comes from ancient Babylon), acquaint with the sexagesimal system of calculus and its basic concepts - degree, minute, second.
The creative process
After deciding which type of protractor to print, you just click on the "Print" button (you can specify several copies), and then cut out the part along the contour.
All kinds of coloring compounds, cotton threads and ribbons of various shades, wool, cotton wool, stickers, beads, rhinestones and bows will find 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 many-fold, it can be pasted onto the cardboard and made a hole in the mark where measurements begin. Despite the fact that this self-made specimen 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. Such joint activities with the child will give you many pleasant moments in the future.
