As I started the other day what will happen if you start play computer games together with your children you could learn of each other I will continue on that track. For an example, last year my daughter AquaVera (by then 5 yo) participated in the first project I ran with Minecraft in School. As most of the building was in the evenings and from home she could, and later also demanded to, join.
As I thought Minecraft would be a hard game to play (I was so wrong!) I told my students they had to build their school and as a creative part, build an own house. It took less than 36 hours to build a minor city and I had to have a second thought about it. During those 36 hours Aquavera also entered the game with an own account and also start build on her own house.
But as it's very fun to build together I asked her what she would like to do and she picked Olivia's house (3315) from Lego Friends.
She had just gotten the Lego kit and we had just built it, therefor she also wanted to have it inside Minecraft. I told her I'm not going to build it alone, she has to help me. We sat together and had the instruction book between us and followed the steps together.
After the house, we also built the Heartlake City Pool (41008) with the water slide, complete with the heart in the bottom of the pool. We also had some discussions about the water and the flow, that you actually can create a slide and play with it inside game.
During these building projects we had done lots of learning, from math and physics (the water slide) to technical drawing (interpret a drawing in 2D to 3D). Both had been troubleshooting where many of the solutions came from her because she wanted to have it exact as in the real LEGO model.
Later she has also been improving the pool with lots of other activities and opportunities for playtimes, like secret underwater tunnels that connect different pools...
