Invite your students to join our scavenger hunt and compete for fun and prizes. The teacher whose class has the most students who successfully complete the challenge will receive a $100 gift card donation for their classroom.
At the end of the contest, students who reach the final secret webpage will be asked to submit an official completion form, including their teacher’s name. Only students who submit a fully completed entry form will count toward the teacher total.
Teacher totals will be based on verified student submissions. To ensure accuracy, we recommend sharing your name with students exactly as you would like it entered.
In the event of a tie, the teacher winner will be determined based on the earliest qualifying student submission times or an additional tie-breaker as determined by the Sponsor.
