Linear Systems

Grade 10s are working on remembering lots of what they learned in grade 9 which will help as we move forward in grade 10.

We’ve done lots of patterning, and tables and graphs and equations. Today I gave groups a pattern rule to model with blocks, then to line up the blocks from each figure vertically, and place a dot at the top left corner. Once groups had one pattern modelled, I gave another pattern to do on the same axes.

We then put all the graphs up on he boards and consolidated vocabulary and connected graphical features to parts of the equations.

We talked about parallel lines never crossing because they have the same slope. We compared steep and shallow slopes, we looked at rise and run, and positive and negative slopes. We saw points of intersection, some we need to estimate. We looked at y intercepts. We also had one group that wanted a challenge to do one that’s not a line.

We’ll start to solve systems by graphing next.
