This is the 2014 version of this unit. For the 2015 version, go here.

Whether you're teaching or studying a unit for the first time, one of the first questions that always pops up is "What are we going to learn?". It is usually followed very closely by "Why should I learn that?" In this post, I hope to answer both those questions within the context of the Ontario grade 8 curriculum. As a teacher, this chapter will be most useful to other teachers, since the lesson plans are written from that perspective. However, the lessons could be just as useful as review for students who have already covered the material with a teacher, tutor or some other mentor.

**Year at a Glance.** In the context of the overall year, this is chapter 1, "Number Relationships". Links will become active as chapters come online. All links should be up by the end of 2014. Here is the post I wrote on my year-long lesson plans. And here's the list of chapters:
