These task cards are great way to get students thinking deeper about place value. The cards can be used as a whole class activity or for early finishers. I like to place them around the room and have my students walk around and answer the problems, it's a great way to incorporate movement into your math lesson. The QR codes are a great motivator for students and I love that they can check their own work! Have fun!!!
** Be sure you have a device that can scan the QR codes. An iPod, iPad, smart phone or Android device should work great. I like to use the app Scan for QR codes.
