If you feel the need for extra help, or if you just want to check to see if your work is correct, you are encouraged to do that. I have the updated days and times posted outside of my room each week. If I am not available on the day that you need help, in my classroom, I have a list of EVERY math teacher's tutoring times. You are encouraged to seek assistance from any teacher of the same content area.
Even though I may not be available, I have placed links for notes and homework on our google classroom. I also encourage students to utilize YouTube and/or Khan Academy. When students type in the topic of concern in to the seach bar for YouTube, many helpful videos will appear.
