The 2021-2022 school year has now begun! It is our goal that all student receive an engaging and appropriately challenging experience in math this year at York. 

If students encounter hurdles that require support, please have them engage in the following:

1. Connect with their teacher in-class by sharing challenges

2. Request to set up a meeting with teacher outside of class during their available periods (see course syllabus for more details)

3. Visit the newly renovated Math Lab from 7:00 am - 4:15 pm and during all periods of the day where a certified math teacher will be available to answer questions. Check out this video, made by senior student Ella Lawton, to learn more about the Math Lab! 

4. Visit Study Tables in the Learning Commons during periods 4, 5, and 6 

5. Sign up for a Peer Tutor 

6. Access more student support resources here
