To ensure the student actually learns the material, consider these "useful" approaches:
Ensure you are looking at the version that matches your workbook's edition year (e.g., 2023 or 2024), as exercise numbering can occasionally shift between reprints.
Have the student complete the exercise first, then use the GDZ together to find and discuss any mistakes.
Use the answers to quickly check homework without having to solve every grammar puzzle yourself.
Focuses on the alphabet, speech, sounds and letters, syllables, and basic spelling rules (e.g., "zhi-shi", "cha-shcha").
Often includes detailed explanations or "hints" rather than just the final answer, which is better for learning. How to Use GDZ Responsibly
