The Number Lab's 100 Chart is unique in that it is flipped, with numbers growing greater as you move "up" the chart, which provides a different level of support for kids when they use the chart as a model. This poster-sized vinyl version is 3 feet long x 2 feet wide and has two red grommets at the top for easy display. It ships rolled in a cardboard tube.
