It's the last day of school before the holidays. On one hand, no work, no remembering to go to things, and no worrying about not getting stuff done on time. On the other, it's really lonely.
We had our Year 8 cafe this week, which went pretty well. We got our food cooked on time and everyone seemed to like it.
We've lately just been doing short maths exercises on probability, tree diagrams and such. They're pretty easy. Say you had two coins. When you toss the first coin you get either heads or tails, and same for the second coin. First you would have two branches of either 'h' or 't', and from each of those you would have two more branches, one for the head that the second coin could end up on and one for the tail.
In the end, it should look something like this, except more like two triangles on the end:
