The teacher will be able to check students have met these learning objectives through starter activities, discussion questions, mini AfL tasks and practice questions for students to complete

Declaimer: Please refrain from purchasing this popular resource for an interview lesson or a formal observation. This is because planning your own lessons, including using your own lesson PowerPoints, is a fundamental skill of a qualified/unqualified teacher that will be assessed during the scenarios outlined above
