I have a year 10 maths class on the C/D borderline. I feel that how I am teaching them is good, however they are completely demotivated. They would rather chat and do very little work in class. They also do very little revision at home and so got very poor grades in their mock exams. I am concerned that they will drastically underachieve in their GCSE exams unless I implement some raising attainment strategies with them. Does anynody have any suggestions?
