This kit contains a title poster, 4 levels, and an encouragement poster all in a single PDF file. The levels are 4-blue, 3-green, 2-yellow, 1-pink.
I searched far and wide for pre-made Levels of Understanding posters that were not filled with verbiage, had four levels, clear graphics, and direct wording. I was at a loss for finding something to meet my criteria and made my own. Feel free to take advantage of my work. The graphics are from a freeware site.
