Thank you very much GameCorpStudio, Glerikud and TRMG for your interesting inputs.
I am indeed thinking of teach her by example with a small game. Something easy and quickly to do. For example an orange tree, a mango tree or banana tree (actually a plant but most people call it tree). The player has to catch the falling fruits in the basket.
Also after the basic project is completed, she can add more features. Like flowers in the grass, when the player walks over them they break and a point is subtracted, when he/she jumps over it there is an extra point. There can be a pond added, when the player stumbles in it, the game is over. There are so much possibilities with this theme, she has to use her fantasy.
I got that idea based on the input here. It is a small project but there is already a lot in it. And she will quickly see the results of her work. She likes drawing, so she can draw the objects of the game herself.
For me, the fun and educational touch are equally important. In her free time, learning has to be fun for her. She is a very fast learner especially with computer related things. She learns faster when she can try out and do things herself. She is quickly bored when sitting near her and explaining while she sit there. When sitting near her and explain while she does the actions keep her focussed on the task she is accomplishing.
I already downloaded and watched the suggested tutorial and that is a very good starting point. From there on, we can go further.
I will also buy and download some sprite packs, so she has a nice library where she can choose the sprites, she cannot or does not want to draw.
I appreciate all your input very much and again thank you.
Wish you all a very nice day and all the best.
Karabo and Chris
