Use cards as task cards for early finishers, scoot them from one student to another, or use as a quiz. Students will multiply to find area, add to find the perimeter, or the sum of 2 areas or perimeters, subtract to find the difference between 2 areas or perimeters, and add and subtract to find missing sides in a given shape. Students can check their own answers using the QR codes! A great review of Area and Perimeter!
Project Based Learning: Obstacle Race Course with Area and Perimeter (PBL)
Let students learn how math concepts are connected to the real-world as they design their own OBSTACLE RACE COURSE! Focusing on Area and Perimeter means--Math is everywhere in this project based learning activity (PBL). Designing, creating, and problem solving are key features of this resource. Design An Obstacle Course! $
I would use QR Codes in the classroom for a number of activities. Whether it was literacy, math, science or any subject, QR codes get students used to using technology in a fun and creative way. The student would grab a cube and complete each of the activities as part of a daily task. I would use this in my 1st grade classroom.
