<p>Slides for introducing plotting graphs.</p> <p>This is Part 2 - It builds directly on Part 1 to an x-axis that goes negative and shows the linear continuation into negative y, while the quadratic remains positive in terms of y.</p> <p>Part 2 sees the students plot a linear and a quadratic function but only for positive values of x. I get them to do both on a single sheet of A4 graph paper.</p> <p>Lots of “what do you notice”, “what’s the same; what’s different” opportunities.</p> <p>Students enjoy this and it works well as a double maths (approx 2 hours) session. It went down a storm with a capable Year 8 class.</p> <p>I feel there’s real value in them creating a graph from a blank piece of graph paper, from start to finish.</p>

<p>Worded problems focusing mainly on compound depreciation, with 2 compound interest/appreciation questions thrown in. I have tried to make these at least somewhat realistic/real world type problems.</p> <p>The accompanying handout has the first problem almost completed to scaffold students and help get the task moving.</p> <p>Initially designed for a mixed ability Year 8 group, this obviously could be used as a refresher, or cropped into a shorter starter task.</p> <p>Hope it’s useful to someone.</p> <p>Cheers.</p>

<p>A grid of surds (by row) and steps to simplify them (by column). Students are expected to fill in the blanks on the grid. The grid is scaffolded and slowly expects the students to do more.</p> <p>This worked well with my Year 9s and served as a useful resource in their books that they could refer back to as we progressed.</p> <p>Given as a printable Powerpoint slide with answers to follow up with on a second slide.</p>
