Code breaker:Quadratic graphs
Three parabolas on one grid: read the roots, intercepts, turning points and lines of symmetry, solve an equation from a curve, then work out y values for a table at x = −2. The Code Box includes the answers you get from a sign slip or from squaring −2 to get −4. One per A4.
A free key stage 3 and GCSE algebra puzzle with answers, spec code A11. It goes with the lessons on quadratic graphs: roots and turning points and plotting quadratic graphs.
