This is a matching activity where students match the way inequalities are expressed. Students must match inequality notation algebraically, on a number line, interval, and in written form. Contains 8 number line graphs, 8 expressions in interval notation, 8 expressions written in English, and 8 algebraic expressions, that students sort, making groups of four. Each card meaures 2.5" by 3.5". Purchase is for the file only, buyer will need to print the cards and cut them out. I have also used just the graph deck, and had students determine the other forms on their own. The flexibility allows differentiation within the same class, and challenges the stronger students. Answer and note cards are included.
