This listing is for 3 posters sized to 24 x 36. Send to a local print company for an excellent addition to your classroom. I suggest searching out a company that prints blueprints. In my experience, these companies offer cheap poster printing. Links to the posters in this bundle are listed below.

Cross Cutting Concepts Poster
NGSS anchor posters are an excellent way to focus student attention on the cross-cutting concepts and science and engineering practices. Use arrows with adhesive (I use magnets on back of poster and arrow) to highlight current cross-cutting concepts and science and engineering practices during instruction.
