Teachers: For a copy of this chart that just fits a normal sheet of copy paper, email us and we'll send a PDF.  We also have a file that prints two tables on one sheet of paper. Do your students a favor. If you copy this image, the small print will not be in focus. Ask us for the PDF instead. Print from the PDF we email, and everything will be needle sharp. We will send a pdf of each file.

 

For classroom use, there is no copyright issue and its use is unlimited for teaching. Multiple copies are allowed and you can give them to students.

We can supply this to anyone for personal use, but not for reproduction.

To contact us, click here. This won't trigger a flood of emails. We rarely send emails and only if you sign up. There's enough in our inboxes already!
