Pictographs and Bar Graphs

We have been discussing interpreting and creating pictographs and bar graphs. The students have done fairly well interpreting the graphs but have shown some confusion is setting up a KEY for their pictographs. Another point of confusion for some is comparing two sets of data when looking at the graphs. They understand that one category is more than another but they have a hard time decoding some of the language. I am including a few short videos that they can use to review.
