The books are clearly structured with one new theoretical issue introduced per page. The ebooks include both examples and assignments with answers. Assignment pages are found at the end of each chapter. These can be used as lesson exit tickets to check that the student has mastered the theory introduced in the chapter.

4f Note provides a powerful collection of tools for digital mathematics education. The rich text editor uses traditional mathematical notation for formulas, so mathematical text can be written and edited in a simple and straightforward way.  You can add a number of different mathematical content elements to a page, like function graphs, geometric figures, displayed formulas, calculations in traditional format as well as in structured derivation format, sign charts and general mathematical tables.

The eMath textbooks used in the course are developed by Math teachers from Finland, Sweden and Estonia. The books follow a teaching approach that uses the Structured Derivations methodology, where the idea is that every step has an explicit justification. This makes it easy to follow the examples that explain the theory. At the same time the approach forces the student to reflect on what they are doing. The books also introduce the students to logic, a step often skipped in school, but without which mathematics becomes magic instead of reasonable and understandable.
