My Lessons include:

• Visually appealing graphics that encourage engagement throughout a lesson.
• ‘Do now/Starter’ activities with music to encourage fast and easy settling as the pupils arrive to lesson.
• Progress steps: By having the student’s track their own progress, it creates ownership of goal achievement. The graphic representation of the students’ progress can be highly motivating. If improvements are not achieved, students can reflect on what changes need to be made to the intervention plan.
• Peer and self-assessments (AfL) encouraging use of green pen self-assessment and purple pen peer assessment . This can be edited to meet the expectations of your school policy
• Formative assessments to consolidate learning throughout (exam-style questioning, linking questions)
• Plenary activities.
• Extensions and challenge questions to reach higher ability students.
• On screen timers to aid lesson plan and pupil focus.
• Implementing subject specific key words throughout to encourage literacy
