"Stack the Countries" is listed for ages 4+. While I imagine it might be best for 8+, due to the degree of world knowledge and reading required, Mag actually loves it at age 5! Most often, I read the questions to her, and she asks for hints for the correct response... but even that M.O. fosters great world awareness. She is getting exposure to names of countries, visualizing their relative sizes, and hearing facts about each... even remembering many international landmarks, like The Great Wall of China and Ayers Rock. Not bad for a free app!
