Now that students know how to use a ruler, they will challenge their measuring skills by applying their knowledge to basic perimeter facts. A “Perimeter Question Card” will be placed on each desk. Students will move from desk to desk. At each desk, students will read the math fact card and write the answer on the “Perimeter Question Card” grid worksheet. When students hear the word, “SCOOT”, they move to the next desk. Students visit each desk in the classroom and answer all of the question cards.
