This is a consolidation lesson on a variety of topics involving quadratics for a higher tier GCSE class. There are 4 rounds: expanding double brackets, factorising quadratics, completing the square and solving quadratics. Each has 3 sets of questions that are differentiated - harder questions are worth more points. Students can get in teams of up to 3, but I’ve implemented a bonus to those who work in smaller groups to keep it fair. There are also some random bonus rounds thrown in to keep students engaged. I’ve also provided a scoresheet that students can track their points on and answers are included.
