Simulator for switching from a narrow line to a wide

"System for switching from a narrow line to a wide" is a new type of textbook. It is training in nature, addressed to primary school students.
The main goal of the simulator is to help the child gradually and smoothly switch to a wide ruler. The transition is based on the graphic principle of drawing the written letters of the Russian alphabet (from lines to oval) At the same time, not only the inclination, but also the height of the letters, next to the usual size (the height of the letters in the double line) is considered a reduced option (the desired height of the letters for a wide ruler).
Each page is divided into two parts, leading elements of different sizes are given at the top. A sample drawing of the letter or connection of letters is presented in red. The letters in a blue pale color need to be circled by executing the mark according to the sample, to continue until the end of the working field, which is also represented in pale blue for orientation.
We hope that this simulator will help children transition from a double line to a wide
