I want to help my 8 year old granddaughter in Brazil with her maths, so anything I set up needs to be fairly simple for her to interact. She is house bound because of the severe COVID-19 restrictions in Sao Paulo. Her dad can help her out to get started, but ideally she should be able to run with the maths lessons by herself.

So has anyone had a similar experience and can suggest any of the Miro resources where I should start?

I should note that I am a new user of Miro, although have plenty of experience with various Mind Map software packages.
