Repetition is the mother of teaching. For the formation of competent writing, it is simply necessary. It's hard to think of anything more boring, though. The way out is to make the repetition entertaining. For this, a series of funny notebooks in the Russian language for elementary school students was invented. The text of the notebook is saturated with examples of one of the main orthograms. Exercises are selected for the chapter to automate the skill of applying the rule in writing. Students can work with a notebook kk in the lesson, or independently, at home.
