7. Build your own family business
If you have slightly older children and want to do something that can extend over a longer period, you can build your own family business. You don't have to be an entrepreneur yourself to build a family business. Basically, it's about finding out who you are as a family, what interests and skills you each have. Then you can begin to describe the different interests and play around with what concepts you can make together. There may also be several kinds of products or services in your family. Then you can talk about who could use those services - what problem you can solve and for whom.
This game can last for a really long time and can end up being a reality if you work with it seriously. On the web there are many different business model exercises that you can look at. There are both some who are very business-like and some who are for visual people and also some for children if you are leading a bit.
