1 Quadratic Equations – Mixed – Card Match
In this activity students work individually or in groups to match questions and answers. Instead of cutting out cards, students can letter questions and answers that go together.

2 Printing To print handouts from slides -
Select the slide from the left. Then click: File > Print > ‘Print Current Slide’ To print multiple slides - Click on a section title to highlight all those slides, or press ‘Ctrl’ at the same time as selecting slides to highlight more than one. Then click: File > Print > ‘Print Selection’ To print double-sided handouts - Highlight both slides before using ‘Print Selection’. Choose ‘Print on Both Sides’ and ‘Flip on Short Edge’.

4 Solving Quadratic Equations Checklist Does it need rearranging?
𝑥2+8𝑥+4=0 2𝑥2−7=0 𝑥2−𝑥−12=0 Solving Quadratic Equations Checklist Does it need rearranging? Rearrange to find a, b & c Does b = 0 ? Rearrange to solve Does c = 0 ? Factorise into a single bracket Can you factorise quickly? (with or without coefficients) Factorise into double brackets. Does b half? Complete the square Quadratic Formula 𝑥= −𝑏± 𝑏 2 −4𝑎𝑐 2𝑎
