The set for the second class includes textbooks for the first and second half of the year and a task in six parts - three parts for six months.
In the middle of the task book there are sheets of stickers. For the convenience of the teacher, the tasks are conventionally divided into lessons, and lessons - into weeks. Inside the lesson, the tasks are located in the order of increasing complexity (the last two tasks in the lesson are usually quite difficult and optional) Depending on the individual characteristics of the children, the teacher can change the speed and order of passing the material.
