This Smartobard unit was designed to teach students with a cognitive disability, and students with autism. The unit covers 5 Ecosystems: Ocean, Rainforest, Plains, Desert, and Tundra. Each Ecosystem chapter comes with picture symbols for students who cannot read print, and multiple choice questions at the end of each chapter. This unit offers interactive pages where students can group animals in their appropriate Eco-Systems. This lesson would also be suitable for K-2 students.
