In science, one of our main goals is to teach them how to read and analyze graphs. I've created these graph analysis activities based on the IVFconcept from Language Arts. Identify, Verb, Finish your thought. This product includes the graph I use for my first IVF graph of the year...income as it relates to educational level.
The file is a word file so it is easy to change of the graph to fit with your content (some years I did these once a week, some once per test). You could also include data table instead.
The first time I teach this, we do it whole class. Second time, I start them, then they finish. Depending on your kids, after a few lessons, they will be able to analyze a graph completely without your help!
