Morning all, just the one activity for all today. If you usually do developing, I suggest going questions 1-3 and leaving the reasoning and problem solving (unless you're feeling confident with it). For those who usually do expected and greater depth, have a go at whole activity sheet.
With regards to the whole class guidance, in class we got stuck on the last set of questions. So, if you've also found it challenging at home, watch part 4 as we work through these together.
