I use this for homework, with one week to complete and usually about 30 minutes in class for questions towards the end of the week. The assignment is designed for students to find mean, median, mode, range, standard deviation, and histograms.
My students will model their equation or inequality on the left in the mat and graph it on the number line to the right. It has helped my kids see the modeling and the graph on the same page, side by side.
