Any given activity is more entertaining for children if it can be conducted on a computer screen. This is a sad but apparently unalterable fact of modern life.
So, one rather fun educational tool which families can use for free is the Kahoot! quiz app. It allows you to build your own quizzes, and provide four multiple-choice answers. You can decorate the questions, and you can open the contests to anyone to whom you have given the PIN. So they provide a way to keep the kids being educated in a way they might actually enjoy, and it makes for a social activity. It’s worth a try.
Enjoy the weekend.
