Got your 3M clips ready? This sturdy hassle-free clipchart has been printed on 13 ounce banner material and sewn at the seams for a beautiful finish. It has 3 grommets placed at the top for you to hang as soon as you receive. Finished product measures 12 x 36 inches. A class of 20 students fits beautifully on the chart. It can be adjusted to fit a co-teach scenario. At the end of the year just roll it up and tuck it away. You will need to allow for time to flatten out if you do decide to roll it up as the chart will curl. Dampen cloth with water only if needed to clean.
