Here's what other teachers say...

Lesson Ninja is a fantastic tool for language learning. It's simple and intuitive on both ends (for students and teachers). I really appreciate the option to have customized links to different versions of the same set (test mode, with/without wordpool or timer etc.) without multiple unnecessary copies of the set itself. The "randomize" option is great for speaking prompts and discussion questions. I highly recommend including it in your classes.

The whole thing looks cool, slick, and modern. It’s been a week and I already know I’ll be a regular user. With Ninja, I prepare revision for my students almost automatically, in max 10 minutes. My students feel that I’m extremely well-prepared as they see their own words and phrases in the link. In the digital era, such solutions are a hit.

I’m at a loss for words at how useful and time-saving Lesson Ninja is for me. It takes me seconds, literally, to prepare a good exercise which draws my students’ attention to the important grammar or vocab topics they need to focus on. Lesson Ninja site is a dream come true for me as a teacher. User-friendly options - both for teachers and their students - only add to the uniqueness of the site. It’s definitely worth recommending to those who are in need of more pleasure and less drama in their lesson preparation time.
