When your students reach a Full Mathalon, they have access to a 3D/AR trophy they can take a picture of! You may have to assist them in taking their photo. The 3D/AR Trophy can only be taken as a picture from a front-facing mobile device. It does not work with selfie view or with cameras on laptops and Chromebooks. Your students can find access to the 3D/AR Full Mathalon Trophy on the Mathalon page in their accounts.
