My school was built in 1929 (literally) and I'm in one of the only original classrooms, so I'm all about jazzing up our classroom in as many ways as possible. I made these letter & number banners to decorate our door with our room number and made banners with my name and my para's names.
You can download the letters and numbers for free here. Then use a hole punch to make a hole at the top and place on a string. I taped the string in place on the bag with clear tape to hold in place. I also laminated my banners so they would last longer.
