Arithmetic and visual geometry. 6th grade. Tasks

The book contains tasks of slightly increased complexity in arithmetic and visual geometry for students in grade 6. These are mainly tasks for ingenuity and entertaining tasks. Many of them are non -standard, but their solution does not require knowledge that go beyond the 6th grade program.
The location of tasks for the chapters follows the procedure for the presentation of most textbooks. At the end, the answers are first given, and then detailed solutions (with the exception of cases when the answer itself is already a complete decision)
The book is intended for students in grade 6 who want to learn how to solve problems that are a little more complex than those offered in textbooks, as well as for teachers and parents
