Students divide a parking lot into evenly spaced sections based on various widths of the dividers. Students will generalize the experience to write equations to help evenly space any size parking lot with any size dividers and any number of dividers.

This interactive web tool and lesson helps students count large numbers of things by using the mathematical structures of area and proportionality. Students use a ratio table to keep track of their work as they count the number of tiles required to cover a floor, and the time required to put those tiles in place.

This resource is an interactive activity that helps students analyze and determine whether the plotted data is a linear, quadratic, or exponential function.  If the teacher logs in, a code pops up for students to enter into their own device and student responses are collected and reported.  It would be a great activity to use with iPads.

This activity fosters formal vocabulary development of linear equations.  At the same time, it solidifies important linear equation concepts such as: slope, intercepts, and also develops good questioning techniques.  Students must ask questions to narrow the field of suspect linear equations down to one.

This activity is designed to facilitate vocabulary rich conversations about geometric transformations.  The students are randomly paired to play Guess Who games with transformations of shapes. Terms used may include translation, rotation, reflection, dilation, scale factor, image, and pre-image.

This lesson helps student develop a concrete understanding of the connection between a graph and the situation it models.  Students start by graphing a simple case with a chance to check their work, then move on to more complicated cases.  Students must also answer extenstion questions.  Finally, students create their own situation and can try those created by their peers.  The teacher can view student products throughout and after the activity.
