Card game:Grandma's Game of Knots and Whys of Science

McLoughlin Brothers introduced the successful "Grandmama's" series of educational card games in 1887. Players assumed the roles of "scholars" and designated one participant to act as "preceptor." Scholars tested their knowledge answering questions posed on cards, and the preceptor confirmed or corrected them from a companion book of answers. This version, made by Milton Bradley, is called "Grandma's" instead of "Grandmama's." Milton Bradley eventually purchased McLoughlin Brothers. This game was made before that purchase.
