We've been doing linear graphs with our Year 8 group. I don't want to make a big thing of being able to draw linear graphs without a table at this stage, but I do want them to notice that the numbers in the equation reappear as features of the line they draw.
My first attempt at this lesson left them a bit lost - I left it too open ended and they didn't really know what they were working towards. I also didn't have any values in the tables for the equation, and most of them weren't confident enough to come up with their own values.
I've now done a new worksheet on a SMART Notebook file, and exported it to PDF for printing/those of you not using SMARTBoards. It leads them through the process much more closely so tomorrow I shouldn't be swamped with students who don't get it, and I can focus on the (hopefully) smaller number who need my assistance.
There is actually no mention of the words 'gradient' or 'y-intercept' in the worksheet but I will certainly mention those terms to selected students, and possibly the whole class if they seem happy enough.
