A wedge of lime for me

Here's a project the kids have enjoyed.  Year 9's have made these as a first project to get them thinking about skills and managing their equipment.  There are not many pins left lying around at the end of the lesson now they are using these babies! I was passed a copy from a friend via Claire B at a local school.  I don't know if Claire created this originally but it's terrific!  I developed these photo tutorial instructions  - a bit lengthy - in an effort to make the instructions very explicit and visual...did I achieve that? I have to admit the instructions I used with my first group were ignored in favour of 'what do I do now?' (say with bit of a whine for authenticity...:) I'd love to try these again, or if you do, please let  me know!

What do you use in the classroom?  Did you have something like this when you were at school?

My next challenge is to share the tutorial with you!  I'll publish this now and go do a bit more research!
