Welshmathsman Resources Plotting Quadratic Graphs Starters and Worksheets

This is a series of interactive whiteboard starter resources to deliver:

• Plotting y=+ax2
• Plotting y=-ax2
• Plotting y=+ax2 ±bx ±c
• Plotting y=-ax2 ±bx ±c

There are four versions of each different quadratic graph plotter. Each version comes as horizontal or vertical table formats depending on the way you teach it.

All versions randomly generate curves to plot, select a random x-axis range and calculate and set the minimum and maximum value of the y-axis so the graph can be plotted.

The autoplot version randomly generates a question then calculates the coordinates to plot, showing full workings and plots the curve one point at a time. There is a variable delay timer so you can ask students the correct value using for instance mini-whiteboards.

The ‘BLANK’ version randomly generates a question to plot and allows you to fill in the table by typing in correct answers or you can use ‘Answers’ button and the sheet will fill in the correct solution showing full workings

The resources are written using EXCEL 2013 and include VBA code to randomise questions and include countdown timers. Worksheets are formatted for printing on a single sheet of A4.
