It made be noted that my lessons tend to follow a format. When creating a unit I try to keep a set format for the structure of class lessons. I find that if the lessons have a set format that the students can know and expect they tend to concentrate and absorb the content more readily, because the lesson's organization is second nature.
In this unit each lesson would have a whole group lesson to introduce the system. It would then have a physical activity, and then a small project to be completed in partners. Then we would come together to look at our results and the students would return to their seats for independent work or reflection.
