Prepare and use activities to practice division facts. Use them in mental and oral starters in your own and other classrooms

© Crown copyright 2003 Primary National Strategy Slide 4.4 Putting ideas into practice Prepare and teach two lessons on division – one to your own class and one to a colleague’s class (preferably a different age group). Allow about 2 hours plus some normal teaching time with your own class for this task. Choose the lessons from those in Participant’s pack 2. Adapt them as necessary to suit the pupils that you will teach. After each lesson, complete the evaluation form provided in the pack. Be prepared to discuss the lessons on Day 3 of the course.

Pick a problem from the paper Problems to solve, suitable for the pupils in your class. Give it to the pupils to tackle as part of a normal lesson. Identify one solution based on a systematic approach, and one where it is not. Bring the two examples with you to Day 3 of the course. Allow about 1 hour plus about 30 minutes normal teaching time with your own class for this task.
