Someone mentioned this software on a Listserv I am on (thanks Pauline!) and I thought it should be passed on.
If you can’t afford Adobe Acrobat, you can use PrimoPDF (a free download) to make PDF files.
Even better, if you need a student to send you files in a “standard format,” the student can use the PrimoOnline file converter to upload a single file and receive the converted PDF file as an attachment to an email. This means there is no software download required (you know how students are with installing software … ). Also, if you’re on a computer with no PDF capability, you could use PrimoOnline too. Personally, I’m bookmarking this one!
Much of the work that I do to create content like math games, creative math activities, and modern application problems is unsupported. I teach as an adjunct and do not receive a full-time salary from any of my endeavors. Graphs In The World (GITW) is also a project unsupported by any kind of grant or salary. If you regularly use these materials, and it saves you time, consider donating a small amount per month to keep these resources coming.
