I'm sat by the side of the pool at the Math watching Jake have his swimming lesson with Rebecca. She's trying to get him to swim with his head in the water and breathe to the side. Progress is being made, and this definitely qualifies as more advanced swimming than I can manage. I'm sure that Jake would be amused to hear stories of my attempts to swim in this pool when I was 11. I was in the bottom group and was hopeless - trying to hop across while no-one was looking!
