Blog posts have been written here covering each of the game types that I use at this time. All of these games use rules from sources that have a long history of fun. And every new game I learn seems to be a twist on an old one.
Each game we play we look for information to earn points; pairs, sets, categories, or sequences. When you learn a new game think about 'what you are searching for' or 'how you earn points.' Look for fun, simple rules that you could use with the information (pairs, sets, categories, or sequences) that your kids need to memorize.
I encourage you to use this ancient tool to help your kids memorize information.
