Make factorizing quadratics easy. (English)
Math. Sch. (Leicester) 38, No. 2, 38-41 (2009).
From the introduction: As many teachers have found, teaching Key Stage 4 students to factorize quadratics such as $3x^2+11x-4$ can be a challenge. To rise to this challenge, I have developed a strategy and resources which will help students engage with their learning. They have been used in my own school and with students and teachers in other schools. The approach makes use of a template which has four rows of squares (I shall refer to them as boxes), arranged in a \lq cross shape\rq .
