For teachers

How teachers use it

• A link in homework. Every material has a permanent address that can be pasted into an e-diary or class chat.
• Printing. Every sheet has an A5 PDF and a “two sheets on A4” version with a cut line.
• A QR code on each sheet opens the online version of the same material.

The materials supplement textbooks; they do not replace them. Lessons are in Russian.
