Grade 9 – Algebraic Thinking Tasks

Hello to the hard-working and deep-thinking teachers of Coquitlam!

I have attached select slides from today’s presentation on algebraic thinking, to remind you of the tasks that we did as a group, their purpose and how they connect to the PLOs for the Grade 9 Patterns and the Grade 9 Variables and Equations strands.  Remember that the curriculum is very clear that students must model their algebraic thought – and we can do so with materials like pattern blocks (the shapes you used today to make your growing patterns and tessellations), base ten blocks, colour tiles, two-colour counters and algebra tiles.

Each of these materials is available through  The selection and rates are better if you access through the elementary math catalogue rather than the secondary one…
