Here’s a fun little monkey-themed prime and composite number sort. Your kids will love scanning the QR codes when they’re finished sorting to self-check their work. All you will need is a device that can read QR codes (iPod Touch, iPad, tablet, or laptop/desktop with a camera).
This sort goes great with my new jungle-themed QR code math centers
