Hi everyone, welcome to grade 9!

I hope to put class notes and further explanations here to help you to understand and keep up with the concepts we are studying this year in math.  If you have any requests, Let me know via e-mail or simply ask in class.  Remember the only silly question is the one you don’t ask! 

Have fun, work hard, get involved!
