I’ve tried many platforms, but this one really stands out. The lesson builder is intuitive, and the variety of exercises keeps my students engaged. It makes online teaching a breeze!

My students stay motivated, and I have more time to focus on teaching rather than planning.

It is such a timesaver! I used to spend 3+ hours to prepare one lesson, now it takes up to 15 minutes. The same goes for my students. Now they can check their HW in one click! Our lessons are much more productive with Class Builder.

I definitely recommend trying Class Builder!
It makes lesson planning so much faster. It’s also super convenient to prepare extra practice tasks during or right after the lesson.

Here is a fantastic tool in case you need to create a lesson from scratch or add some extra tasks on a particular topic. It’s easy to navigate and lets you combine whatever stages of your lesson you like, with as many tasks as you need!
