Awesome idea Delia! I wish I had put all of the vocabulary together in one of my posts. This makes it simple for anyone viewing you blog, to catch up on some forgotten vocab for our final. I also liked how you divided the words up so that they follow the order of our lessons. This makes it easy to view the words in the order the sections are in.
ReplyDeleteDelia,
ReplyDeleteI love that you posted the vocabulary from class! This is a post I will be using to study for the final. It's also inspired me to include a vocabulary list if I end up posting online for my classroom or business. My students should be able to study if they really want to, even if they lost their papers. Great post :)
