Everything built into the lesson

Not just a planner — Derstina gives you actual lessons with stories, activities, and exercises ready to run live with your student.

📖

Stories for Young Learners

A1 and A2 lessons include fun character stories — Milo the puppy, Luna the cat, Sam the squirrel — to engage children and make vocabulary stick.

🎮

Built-in Games & Activities

Every lesson has interactive games: bingo, charades, story chains, roleplay, and more — all designed to work perfectly over Zoom.

🖥️

Interactive Slide Lessons

Every lesson runs as a polished slide presentation you share on screen — with interactive exercises where students answer question by question and reveal answers on click.

🎓
