Subject: Mathematics (8)
Title: Function Machine
Description: During this lesson, eighth grade students will interpret the perimeter of a train of triangles, squares, trapezoids, or hexagons as a function (for each input, there will be exactly one output). Students will represent their data in a table, as an equation, and graphically.

Title: Supreme Court Welcome
Add Bookmark
Description: In this unit of two lessons, from Illuminations, students experience triangular numbers in an interesting, real world context--the Supreme Court. Through the discovery of patterns, students are able to generate geometric and algebraic representations for the nth triangular number.

Title: Counting Embedded Figures
Add Bookmark
Description: In this lesson, from Illuminations, students look for patterns within a given set of data. After looking at the pattern, students form generalizations for the problem and sharpen their algebraic skills.

Title: Gallery Walk
Add Bookmark
Description: In this lesson, one of a multi-part unit from Illuminations, students view the work of other students in the class and explain their own work. Students move from graph to graph during this time and, without any talking, view the work of their classmates. While on their Gallery Walk, the students think about the data their classmates plotted and whether or not the information accompanying each graph seems appropriate. Each pair of students then stands next to their own work and explains one of the graphs.
