Here's what other teachers say...

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.

A wonderful tool that has been helping me prepare great and strongly motivating warm-up and revision activities, thereby making my classes effortlessly more varied and fun. A range of useful options, such as wordpool and time limits, allows for adjusting each activity to different students' levels if needed. On top of that, the website's simple, minimalist design is really pleasant and user-friendly.

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!
