Over the years, so many parents have told me that they would love a game that they could play with younger children. I've listened, and now I give you two.
Both encourage younger children to question fantasy situations, create stories, and problem-solve.
The "Would you Rather" books take each segment of questions and build upon choices to the next decisions until they must battle their foe through a story built by whatever they have collected, befriended, and selected.
Our other book is the Fantasy and Folklore ABC "Create a Story" Game. Super simple to play. Choose ANY word, then build a tale from the letters related to them. You also have questions for each letter subject to help with writing and ideas.
