These are great posters to hang on your math bulletin board when you are first introducing algebra (or refreshing!) They are aligned with the Common Core and work well with the 6th grade math core and above.
I highly recommend printing them in color, laminating them or putting them in page protectors and then hanging them on your board for kids to refer to often. They are also great for teachers who create interactive notebooks or math word walls. Check the store for more math unit vocabulary posters!
