It’s difficult for modern children to be carried away by something. They like to watch cartoons and play computer games. But smart parents are always able to interest their child. For example, they may suggest that he find a way to draw an envelope without taking his hands off. Read about some of the tricks of this quest below.
Warm up
Before you begin to torment the child with logical tasks, you need to carry out preparatory work with him. Why is it needed? So that the child does not cheat when he begins to puzzle over the question of how to draw an envelope without taking his hands off. After all, the most interesting thing in this problem is that the line should go from point to point continuously.
What tasks can you offer your child as a workout? Of course, the first should be eights. Drawing this number and stress relieves, and the brain cleanses, and the arm trains. In general, a useful exercise. After that, you can move on to drawing rounded shapes. It can be curls or any other squiggles, the main thing is that during the drawing process the child does not tear off a pencil and depict everything in one smooth line.
How to draw a closed envelope
Many parents themselves spent more than one hour before offering such a task to the child. You can also try. But we can immediately upset you - to complete such a task, without a bit of a trick, is simply impossible. Therefore, we will tell you a way that will help you and your child go a little beyond the usual logic in order to understand how to draw a closed envelope without taking your hands off.
We take a sheet of paper and bend the edge from it. Bend it back. Now our task is to draw the top edge of the closed envelope just on the bend line. To make it easier to understand, arrange the points at the ends of the rectangle. We number them starting from the upper left corner. There will be a number one and further clockwise. From the figure 4 to 1, draw a line, now connect 1 to 2 and now draw the diagonal to 4. From 4 to 3 we draw a straight line, and then again the diagonal to 1.
Now we pass to the most interesting. We bend the edge of our sheet and depict a zigzag that forms, as it were, the cap of our envelope. It will go from 1 to 2. It remains to connect 2 and 3 in a straight line - and the puzzle is solved. Fold back part of the sheet. The riddle of how to draw an envelope without taking your hands off can be offered not only to children, but also to friends or colleagues.
How to draw an open envelope
Those who carefully read the previous paragraph and created their own drawing from the description already understood how to answer the question posed above. After all, the solution to the puzzle, how to draw an open envelope without taking your hands off, will be similar to that written in the previous paragraph. Only here you will not have to bend and bend parts of the sheet. The entire image will be made in one line according to the same pattern.
But if you do not want to repeat yourself, then we offer another way that will lead to the same result. How to draw an envelope without taking your hands off in the second way? First, draw a rectangle again with dots and number it again, as in the previous paragraph. From the figure 4 to 2 we draw the diagonal, from 2 to 3 - a straight line, and from 3 to 1 - again the diagonal. Next you need to draw a corner. From 1 to 2, draw a zigzag that marks the top of the envelope. From 2, we return to 1 by a straight line and complete our construction, alternately drawing lines from 1 to 4 and from 4 to 3.
Why do you need such tasks
Such logical tasks need to be performed not only for children, but also for adults. Thanks to them, the human brain strains and begins to work. If you accustom yourself to perform on a similar task every day, after a month you will notice that in critical situations, decisions are generated faster and less effort is spent on this. Students are especially useful to study logic puzzles. Thus, they train creativity and learn to approach non-standard approaches to standard questions.
