Just what I was looking for- thank you!!

really very useful, the I am triangle works well. Thank you.

Nice job - well laid out and a good classroom activity. thanks!

in your worked example you refer to the actual size of image, do you mean actual size of specimen? Could you post a word version of this so that I could alter the wording slightly? I do think however, that this is a really well laid out resource and will prove very helpful, many thanks
