Congrats! This is exactly what we are also doing on Curacao, with My First Bitcoin. Mi primer bitcoin.

You could download the open source book and check the education. There are 10 weeks in there and 10 or more exercises. Each exercise explains a concept.

In lesson 9 I vibecoded a Bitcoin blockchain game that explains hashing, hashing a block, linking blocks together etc.

In the future, when you need to explain more technical stuff you could use these to continue your journey. 

I have opensourced this lesson and all my exercises and games on the github of My First Bitcoin - node Curacao.

Keep up the great work.
