From some of our teachers...

Kids LOVED it. They loved the mix… division, multiplication, everything together :)
The questions were just right for the stage my kids are at
I’ve never had my students focus on maths for 45 minutes before this

Personalised questions for every skill level

Each student gets their own questions. Our AI responds to students' answers in real time, making sure questions are not too hard or too easy.

Want your students to share devices?

With turn-taking, one device can have any number of children on it and students can practice coaching each-other. One student answers a few questions, and then they're prompted to pass to the next one.
