This graphic organizer takes students step by step through the setup of a cumulative frequency table from their data and then the plotting of a cumulative frequency graph. Additionally, the third page of this organizer also walks students through finding the median and lower and upper quartiles from the cumulative frequency graph they created on the previous page (useful for making box plots). Examples are shown throughout. This organizer is useful for students new to the topic, struggling learners, and also any learners who need very concrete instructions for solving these types of problems. Highly recommended for differentiating in mainstream classrooms and for pull-out mathematics classes. During the corresponding lessons, I make these available to all my students. Graphic organizers are also useful for students who have missed lessons and who need to be able to, as independently as possible, catch up to the rest of the class.
