“The Happy Newspaper” is a medium dedicated to positive news created by Emily Coxhead. I am subscribed to the newsletter in the spirit of the teachings about news by late Hans Rosling, who educated me and many others about media bias.
Other news sources quote the elephant population in Kenya has doubled in the last 30 years (BBC, 2020-08-14).
Collaborative Blokus
Collaborative games are so much more fun than competitive. Less quarreling and fighting. More caring about the input of others, learning collaboration. So Ingrid and me turned blokus into a collaborative game
