This is the beginning vocabulary about sampling for Unit 5 in the 7th grade. My students will write down the correct vocabulary word on the back of each card and then store it in the folder. The folder will be glued down in their interactive notebook. The flaps on the folder are used to secure the front section of the folder to the back. I like putting the cards in vertically, so I don't use the top flap, however, some people like to slide the cards in horizontally to make them more secure. There are blank cards included for more vocab as needed. Here is the list I have written out.
