Plotting Quadratic Graphs | I Do, We Do, You Do | Year 9 Maths | Print Free

Build confidence in plotting quadratic graphs with this editable 120-slide Year 9 maths PowerPoint. Pupils move from accurate substitution and value tables to smooth curves, turning points and symmetry, with substantial practice and worked graphical answers throughout.

An 18-graph practice page and a one-page differentiated task give teachers ready-to-use options for independent work. Enlarged examples and additional activities make it easy to adjust the pace and level of support.

WHY CHOOSE THIS LESSON?

• Six paired modelling examples cover quadratics with constant terms, linear terms, negative coefficients and a fractional coefficient. A compact overview leaves room for teacher working, followed by enlarged questions, substitution steps, completed tables and plotted solutions.
• An 18-graph practice page groups related functions on shared grids. Pupils compare changes to the constant, the coefficient of x² and the linear term, helping them connect an equation to the shape and position of its graph.
• One-page differentiation includes six Developing, four Secure and three Greater Depth questions, plus a Super Challenge. Greater Depth moves beyond routine plotting to missing coefficients and explaining why a graph has no x-intercepts.
• Twenty mini-whiteboard checks use short calculations, coordinates, explanations and graph choices. Every question is immediately followed by its answer.
• Clearly labelled axes, readable grids and half-unit subdivisions where needed support accurate plotting. Worked graphs and value tables make checking and feedback straightforward.

TOPICS COVERED

Substituting positive and negative x-values; distinguishing (−3)² from −3²; completing value tables; plotting smooth quadratic curves; identifying maxima and minima; using symmetry; finding y-intercepts; and reasoning about missing coefficients and x-intercepts.

ALSO INCLUDED

Six retrieval questions and answers; six prerequisite checks and answers; four further examples; ten additional plotting activities with answers; a dedicated misconception check; a six-mark exam-style question with worked answer and mark allocation; and three short exit checks with answers.

The Super Challenge applies a quadratic graph to an object’s height, asking pupils to find its maximum height, landing time, time above a given height and the meaningful time interval. The complete solution appears on one slide.
