Here’s my starter activity which students discuss in pairs then present to me on mini-whiteboards. When the students have had time to discuss the matching pairs we talk […]
In recent examiner reports it is noted how important it is for students to understand the properties of a parabola when plotting quadratic graphs on Cartesian axes. Students who have a secure understanding of parabolas can use them to correct miscalculated values in their table of results and are more likely to attain full marks […]
