Rebecca explained the binary numeral system so well that it is hard to replicate that in a poster.  So I created an interactive poster than gives a brief explanation on how a computer recognizes alphabet letters, but allows the student to practice converting decimal numbers into binary ones. I am aiming this at 5/6 grades. Scaffolding would be required.  I created the poster in Adobe Photoshop and it is laminated, so the student can write their answers using a white board marker and then wipe off with tissue. You can print it out in A4 size and just use a plastic sleeve to get the same effect. Saves on paper. #cserTask3
