#BingeThinking = getting some thoughts out of my head.
As far as planning activities to meet the learning objective and planning for differentiation there are two types of lesson:
SERIES: In this lesson activities are planned to occur one after another so that the pupil works their way through the activities. The first activity would be Apprentice level followed by Qualified and then Master. This means that every child has the opportunity to reach Master level and differentiation is by outcome. A SERIES lesson would typically occur at the beginning of a topic and would allow the teacher to assess the children before a PARALLEL lesson.
PARALLEL: In this lesson activities are planned to run simultaneously so that you have children working on Apprentice level tasks while others are working on Qualified or Master level tasks. It is important that children are able to shift between levels and either move up or down as appropriate.
