Crack The Safe – Solving Quadratics
Free
Three “Crack The Safe” activities on solving quadratics, one by factorising, one by completing the square and one by using the quadratic formula; each question (6 on each sheet) has three possible solutions. These allow students to self-check their answers from the possible solutions whilst the teacher can go and help those who require it. I use these for starters or plenaries or as the first task after introducing the topic.
