The boys have been set in their routines. Do seat work/revision/lessons before getting their hands on their Investigating Task activity. The always highlight of every lesson for all my students. I like to give instructions with open endings to allow space for my students to think. This is the interpretation for the boys. Totally different from what my p6 girls did in the previous post. There is no right and no wrong, as the activity still gets them to complete the objectives.
