Using Marzano scales at your schools?
This product features a 8.5 x 11 poster sized scale that can easily be made larger using a poster maker machine. The 8.5 x 11 size comes in color and black and white. You also receive desk sized scales in color.
I like to use clear contact paper to adhere them to my students' desks. You can also add velcro with an icon to show where each student is or even a paper clip to slide up or down. I have my students hold up their number close to their heart throughout my lessons to gauge their level of understanding. You can really make this your own!
