355. Toyota logic

My fabulous colleague, Mr G, has recently been to the local Toyota factory to find out about the Lean model.

The key principles involve efficiency of process. He told me about a school using the Lean model that had tape diagonally along the spines. Students put their folders back in order and the teacher can instantly see if a file is missing. Genius!

Now I happened to be about to cover my textbooks with sticky back plastic. I put duct tape around the spine before covering them. Each book has tape 1cm lower than the previous.

Now you are thinking – that looks nice, but it will never work.

I’ve got news for you – every time I use the textbooks with my class of 34 Year 9 students, they put the books back in order. On the first day I made a big deal of how tidy the books looked and challenged them to put them back tidy. And they did – every lesson!

354. Iced gems

Just a quick idea today. You know the feeling when the multi-pack of sugar paper has dwindled down to just the brown. Great if you want to do trees, bleurgh if you want to do anything else.

I did a tarsia recap with Year 7. There were three different tasks going on and so I photocopied them onto three different colours of paper. The only colour of sugar paper was brown. We went with it. As the class finished their work, we discovered that their work looked like iced biscuits or iced gems. Hence our wall of Algebra Iced Gems:

Some of the cutting and sticking is a bit wobbly, but the class really enjoyed this task and we consolidated a considerable number of skills.
