Mathematics, Grade 7

In this textbook, theory and practice activities have been divided into smaller subsections for a better grasp of the study material. The textbook has also been designed in a way that enables pupils to study on their own. The practice activities can be found in the so-called sliders, where the first slides provide exercises with examples, whereas the latter ones contain more challenging elements. This textbook matches the printed mathematics textbook for Year 7 and offers additional components typical of digital textbooks.
