This printable Bingo game from Smarten Up is a great way for your students to practice reading words that feature OA/EA digraphs. But instead of simple naming, this activity will challenge kids to use their critical thinking skills to identify the word by solving a simple riddle. For example, students must identify the "thing that grows on trees and plants and falls off in the fall," in order to cross the word "leaf" off on their Bingo board. The download includes boards for four players. Perfect for centers or small group work.
