Problems for senior school

At a party, it was observed that each person knew exactly twenty others. Also, for each pair of persons who knew one another, there was exactly one other person whom they both knew

APC-AREA, perimeter and congruency

We continue our Low Floor High Ceiling series in which an activity is chosen – it starts by assigning simple age-appropriate tasks which can be attempted by all the students in the classroom. The complexity of the tasks builds up as the activity proceeds so that students are pushed to their limits as they attempt their work. There is enough work for all, but as the level gets higher, fewer students are able to complete the tasks. The point, however, is that all students are engaged and all of them are able to accomplish at least a part of the whole task
