Around the world is an interactive game that includes all students. You start out by having math question on flashcards that are large enough for students to see. Two students will stand next to one another and be shown one flashcard, the first person that answers the math question correctly moves on and stands next to another student. The winning student from each pair will continue to make its way around the classroom until every student has gone.
