How the Number Sense Challenge works

• The Number Sense Challenge will be held in an online Zoom room, and students may take the test from any suitable physical location as long as they are accompanied by an adult chaperone who agrees to proctor the test, make sure that the student is following instructions, and help ensure that the student's answers are sent to us when each test is over.
• 4:50pm Pacific / 7:50pm Eastern - A link to the online meeting room will be sent to the email address of each student's chaperone of record about 10 minutes before the room opens; please email onlinecontests@mathleague.org if this link is not received by 5 minutes before the time the room is scheduled to open. You will be admitted to the room at the designated check-in time; do not email us before that time asking why we won't let you into the room.
• 5:00pm Pacific / 8:00pm Eastern - Participants will be allowed into the room fifteen minutes before testing starts. When participants arrive they will find a welcome screen and a reminder to take care of all the check-in tasks listed below in the "before the contest" section. During the first ten minutes mathleague.org staff will be available to help those who need technical assistance. Those who have completed the necessary steps are invited to relax and wait for the contest to start.
• 5:15pm Pacific / 8:15pm Eastern - When it is time to start testing the contest director will share the test password with participants. Answers will be filled out on the designated web form. Participants are not to access any other applications on their computer while the timer is running.
• 5:25pm Pacific / 8:25pm Eastern - After the test is over there will be a brief break for students; contest administrators will use this time to assist any students who were unable to successfully submit the answer form.
• 5:30pm Pacific / 8:30pm Eastern - Once the break is over students are invited to stay around for a brief lesson in which mathleague.org staff will review how to do some of the problems on the test. The lesson will last for approximately 20 minutes and will focus on three primary goals: (1) helping new students raise their score to 100, (2) implementing shortcuts to help students solve problems more quickly, and (3) general test-taking strategies. Students may leave the room after the score input is complete if they choose not to watch the lesson.
• 5:50pm Pacific / 8:50pm Eastern - Students are dismissed. Please note that the times listed here are approximate and subject to revision if there are any delays getting the test started. Regardless of any delays, we aim to dismiss students no later than 9pm Eastern. Results for the contest will be added to our online leaderboard within 24 hours of the completion of the contest if possible. Shortly after the results are posted, the week's Number Sense test and a recording of the lesson will be uploaded to a shared folder that chaperones will be able to access.

What you need to do the day of the contest

• Make sure all students you are chaperoning are present and ready to go and that every student has their own computer that is connected to the internet. The computer must have a camera and each student and their surroundings must be visible on camera while testing so we can monitor them just like at an in-person contest (in particular, students may not use an artificial background).
• On each student's computer, click on the invitation link to the meeting room, and turn on the student's camera and join with computer audio. Make sure the student's microphone is muted. Start the chat window and test your sound and video with the tools Zoom provides.
• Click on this link and enter your student's name, confirmation number, and test number, then click submit. Once your information has been correctly submitted, you will reach the login confirmation page.
• Send an email to onlinecontests@mathleague.org if you need any help. We will do our best to help as many people as we can, and those of you who followed the instructions above and got everything taken care of in advance have our thanks.
• Participants are to refrain from any public chatting throughout the contest. Any public chatting will be grounds for dismissal from the contest. Students are also not to talk to anyone at their testing location while the timer is running.
• As a chaperone your job is to monitor the students during the test to ensure they are complying with the rules. DO NOT interact with any student while the test is running or you will disqualify the student from that test. Maintain a suitable distance where you can observe but not disturb the student while the test is going on.
• Students will type their answers directly into the designated web form during the test. At the conclusion of the test, our system will automatically submit answers for students who have not already clicked submit. If you are unable to reach the confirmation page after clicking to submit your answers, please carefully follow the instructions the contest administrators will give to provide additional assistance.
