some maths links and ideas

Today I just saw this brilliant YouTube video about a chef making very thin noodles. The video illustrated the powers of two really well.

Owen reminded me of the video of James Blunt singing about his love for a triangle.

I also read this article today about how to help your child learn the times tables and a book that explores patterns in the times tables. I have decided that both of my year seven classes are going to get frequent times table tests this year because it's an obstacle that must be overcome to feel confident in maths in later years. I'm also planning on doing a lot more mental maths methods teaching this year. We have been talking about the strategies we use when adding or subtracting in our heads. The questions we have been doing started with 14 - 6, for example, and we worked up to 67 - 38. The first part of the scheme of work emphasises written methods, but I think they are less useful in the long run. Students have to be able to calculate in their head, and know when to calculate mentally and when to use a written method (or a calculator).
