I am having trouble opening some of the free worksheets. Any suggestions?
We have tested all materials on a PC and some on a Mac. We are busy converting all worksheets to .pdf files which will require you to have Acrobat Reader version 6 or higher to access the worksheets. You may download the most current version of Acrobat Reader here. If you have recently downloaded Acrobat version 6 you may need to restart your computer, refresh the page you were looking at and try to download again.
