Here's what other teachers say...

Lesson Ninja is an utterly convenient tool to turn authentic materials into engaging class materials instantaneously! I've been enjoying it to the fullest only after a few trial-attempts thanks to its very simple layout. It's even simpler for my students as they can practice materials using just a single link. As an EFL teacher who enjoys preparing up-to-date content for learners, I love it when time-consuming details of material preparation are minimized, and Ninja does exactly that!

I love that Lesson Ninja works no matter what language you’re teaching. It’s an appealing way of learning for my students and also makes life easier for me. I love the import mode - it’s so quick! Configuring the task (enable first letter, show answers, test mode, etc.) before sharing is awesome, too! To me, this is just ingenious. Highly recommended!

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.
