The Nuffield Foundation provide this resource which can be used to introduce the shape and main features of proportional, linear, inverse proportional, and quadratic graphs. Different versions of Excel spreadsheets allow students to explore how the shape and the position of a graph changes when the constants in its equation are altered.
Students will look for connections between the numbers in equations like y = 2x + 3, y = 20/ x , y = x2 + 5x – 3 and the graphs that represent them.
HEALTH and SAFETY
Any use of a resource that includes a practical activity must include a risk assessment. Please note that collections may contain ARCHIVE resources, which were developed at a much earlier date. Since that time there have been significant changes in the rules and guidance affecting laboratory practical work. Further information is provided in our Health and Safety guidance.
