Grandmother Fish is the first book to teach evolution to preschoolers, and School Library Journal calls it “groundbreaking.” The book engages young people by getting them to mimic the actions and sounds of our ancestors. They wiggle like Grandmother Fish and hoot like Grandmother Ape. The book is for ages 3–6, but teachers have also had luck with older students. The book works well for reading to a classroom, and it includes science notes in the back to help guide conversations with young learners. Jonathan will also share exercises that build on Grandmother Fish, helping children understand deep time and our evolutionary history. Clades and its sister game, Clades Prehistoric, are animal-matching games for ages 6 to adult. Players match animals according to what clades they’re in: mammals, arthropods, or sauropsids. Within each clade are three smaller clades, each defined by descent from a common ancestor that swam, walked, or flew. For example, winged insects represent the arthropod clade descended from fliers. Clades features extant animals, including humans. Clades Prehistoric features extinct animals, including dinosaurs, pterosaurs, and mammoths. Both games include science notes about the animals depicted on the cards.
