Let's use technology to go on a Subtraction Scavenger Hunt!
Students will scan QR codes placed around the room and solve the secret subtraction equation. Equations focus on fluently subtracting through 20.
What is a QR Code?
QR Code is a matrix barcode (or two-dimensional code), readable by QR scanners, mobile phones with a camera, and smartphones.
To use the codes, your iPhone, ipad, or IPod will need a QR reader from the app store. These are free and there are many to choose from.
Once the QR reader app is downloaded, use the camera on the device and scan the QR code. It can show you a picture, take you to a website, or reveal a secret message!
This document includes:
