PREFACECrossword puzzle is a universal means of testing students' knowledge. The crossword puzzle can be used at different stages of mastering educational material and at different stages of the lesson: as a means of updating basic knowledge, checking homework, summing up the lesson. The tasks proposed in the crossword puzzle can be completed individually, in pairs and in groups. A crossword puzzle is a means of activating students' cognitive activity.
This collection of crossword puzzles is intended for students of the 5th grade of general education institutions with instruction in Russian, who study according to the mathematics textbook by the authors N.A. Tarasenkova, I.N. Bogatyreva, O.N. Kolomiets, Z.A. Serdyuk.
The crosswords in this collection have a serial number and name corresponding to the numbers and names of paragraphs of the specified textbook (§1-§22 - educational material for the first semester). To successfully complete the crossword puzzle, you need to study the material in the corresponding paragraph and the “Learn more” section.
This manual will help diversify mathematics lessons.
