Algebra and Trigonometry provides a comprehensive exploration of algebraic principles and meets scope and sequence requirements for a typical introductory algebra and trigonometry course.

If you’ve had much experience with Algebra and Geometry, you know that graphs are a thing.

In this lesson, students model the bodies of different sharks using cylinders, and explore how the volume of a cylinder changes when its dimensions change.

In this activity students explore the relationship between the area of a rectangle and the number of squares that make up a border around it.

In this activity there are many different possible solutions, which gives students opportunity to be creative, and to discuss their sense making.

Unfortunately, real world math lessons are sometimes learned from tragedy.

The mathematical foci of this lesson are geometric concepts, location, navigation, direction, and spatial relationships and measurement concepts, using nonstandard units to measure a distance, and the iteration of units, measurement by using the same unit of measure repeatedly to determine the total.

Students participate in an activity in which they develop number sense in and around the shopping mall.

This lesson is designed to allow students to view the work of other students in the class and to explain their own work.
