This week I had the strange pleasure of having both the least and most popular members of staff in my GCSE class.
The most popular is of course, the new student teacher who is being feted by several members of the maths department. The least was the official observer because it’s that time of year again...your graded observation! Guaranteed for several sleepless nights and a week’s worth of stress.
I trialled the 5 minute lesson plan for a session on reverse percentages. Although difficult to make it exciting, I used an email sent by an ex-student asking why she couldn’t figure out a reverse percentage on a payroll. I got the students to write a reply pointing out her mistake and was graded ‘Good’. Resources below.
