From the pictures above this looks like my country coupled with the names I am seeing on the board. Well I am very much happy seeing that bitcoin adoption and teaching is really going globally. However I would suggest to you during your next presentation you should make it more practically to the students for them to see and view how bitcoin looks like, since is a computer class they always expect the class to be more interactive by doing it practical where they could feel and see what they are learning.
This will be great, if Op shows the students some practical example like how to create a wallet and also how to send some transactions that would be more effective than just writing on the board for the kids. Op should use the school's computers i.e if they have any to show them and if the school lacks computer Op can just borrow from a friend and organize the class for them.
And in the process of all this Op might also be opportune to talk about the different types of Bitcoin wallet addresses and also the benefits/advantages that each addresses has.
