Use the number cards on slides #21-24 to numerically label the desks/seats in your classroom (cut each sheet into six number cards). As each student enters the room provide them with an order of operation task card (cut each sheet into four cards) slides #3-8 or #9-14 with QR code answers. Students solve the problem they were provided with and find their seat based on the solution they get. You may notice more than one student attempting to sit in the same seat. Provide students will support and discussion techniques when faced with challenges. Encourage students to attend to precision, construct viable arguments and critique the reasoning of others. Answer keys have been provided on slides #15-20 and also on the cards (#9-14) in the form of QR codes making it quick for you to check solutions with a QR reader on a smart phone, tablet, iPad, etc. I suggest that you laminate the materials to make them more durable.
*** This could be used for a math station/center as well where students match the questions and solution cards for practice.
