ALEX Lesson Plans
Subject: Mathematics (9  12), or Technology Education (9  12) Title: Parallel Photography
Description: Students will use laptops and digital cameras to understand parallel lines, corresponding angles, alternate interior angles, alternate exterior angles, and sameside (consecutive) interior angles. Postersize concept maps will be created by students and posted on the classroom "word wall."
Subject: Mathematics (9  12), or Technology Education (9  12) Title: Polygons All Around Us! (This lesson is geared to a standard high school geometry class.)
Description: This is a handson lesson that introduces students to polygons and their properties. It also promotes visual learning by having students identify how polygons are used in the world around us. Students will be given the opportunity to see the importance of geometry in the construction of almost everything in our world. Students will be able to state properties of different geometric figures. This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.
Subject: Mathematics (8  12) Title: Quadrilaterals
Description: This is an inquiry lesson used to review Algebra 1 objectives by applying them to geometry concepts. Students explore the properties of quadrilaterals and classify them by definition. This lesson can be use in geometry classes. Students in geometry classes can apply theorems and definitions of quadrilaterals rather than as an inquiry lesson.This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.
Thinkfinity Lesson Plans
Subject: Mathematics Title: IGD: Perpendicular Lines
Add Bookmark
Description: This student interactive, from Illuminations, helps students understand and investigate perpendicular lines. Students read a definition, and then use the interactive to explore the properties of two perpendicular lines. Thinkfinity Partner: Illuminations Grade Span: 9,10,11,12
Subject: Mathematics Title: Interactive Geometry Dictionary: Lines in Geometry
Add Bookmark
Description: This student interactive, from Illuminations, explores lines and their importance to geometry. Students can investigate the definitions and properties of perpendicular lines, segments, medians, Euler lines, and more. Thinkfinity Partner: Illuminations Grade Span: 9,10,11,12
Subject: Mathematics Title: IGD: Angle Bisector
Add Bookmark
Description: This student interactive, from Illuminations, helps students understand and investigate angle bisectors. Students read a definition and then construct an angle bisector using the interactive tool. Finally, students take a closer look at the properties of angle bisectors by answering a set of questions and then checking their answers. Thinkfinity Partner: Illuminations Grade Span: 9,10,11,12
Subject: Mathematics Title: IGD: Perpendicular Bisector
Add Bookmark
Description: This student interactive, from Illuminations, helps students understand and investigate perpendicular bisectors, which are lines perpendicular to a segment that divide it into two congruent segments. Students read a definition and then construct a perpendicular bisector of a segment using the interactive tool. Thinkfinity Partner: Illuminations Grade Span: 9,10,11,12
Subject: Mathematics Title: Dividing a Town into Pizza Delivery Regions
Add Bookmark
Description: In this Illuminations lesson, students must determine how to divide a town based on which pizzeria is closest to a given location. To solve this problem, students will construct perpendicular bisectors, find circumcenters, calculate area, and use proportions. Thinkfinity Partner: Illuminations Grade Span: 9,10,11,12
Subject: Mathematics,Social Studies Title: Hospital Map Activity Sheet
Add Bookmark
Description: This student reproducible, from an Illuminations lesson, contains a map of the area wherein students must choose a location to build a new hospital so it is equidistant from Boise, Idaho; Helena, Montana; and Salt Lake City, Utah. Students do their work on a blank transparency and overlay their work onto this map. Thinkfinity Partner: Illuminations Grade Span: 9,10,11,12
