Excellent. Well worth looking at the lesson plan (other pdf's contain resources required.) For this lesson look at previous lesson plans as this is a revision lesson and does not reflect the detail contained in their plans in general. This is written by mathematicians as well as teachers and as such it can help those for whom math is not their strong suit to see the connections between different aspects of a topic. I strongly recommend taking some time to look at some CIMT resources.
