Bar Graphs represent data visually as a series of bars. They are often presented to students in formative assessments. Teachers rarely take the time to create graphs from data for assessments or lessons. I didn’t use them at first either. Creating graphs is time consuming. I needed to do something because my students often missed easy problems when it came to questions from a graph or table. I was often surprised because we covered them during practice for the larger state assessments. It wasn’t until they started to develop their own that they began to make the crucial connections.
