Curated OER
Reflection
Eighth graders use a stencil to make a figure with which they discover the horizontal line of reflection, the vertical line of reflection, and the diagaonal line of reflection using coordinates.
Curated OER
The Proof
Students will construct simple curves on graph paper by connecting a series of points between the vertical and horizontal axes. They share their designs and explain the patterns.
Curated OER
Constructing Perpendiculars
Learners construct perpendicular lines. For this geometry lesson, students use a compass and straight edge to do construction. They start from a point to a line.
Curated OER
Slope Right Up
Students use triangles to find the length and slope of each side. After connecting the vertices, they add points based on their specific instructions. They use the Pythagorean Theorem to complete a worksheet to end the lesson.
Curated OER
Worksheet 27 - Fall 1995
In this math activity, students find the area bounded by the tangent line, the x-axis, and the line x =2. They also describe the graph of the function.
Curated OER
Mapping The Iditarod
Fourth graders watch a video about mapping distances and then calculate the distance their individual mushers travel each day. This occurs each Monday through Friday until each musher has crossed the finish line in Nome Alaska.
Curated OER
Geometric Construction
Seventh graders investigate some concepts associated with geometric shapes. They study the bisector segment and the perpendicular line to a given line. Students conduct analysis with the goal of deepening observation and deduction...
Curated OER
From Where to Where?
Learners find locations based upon their latitude and longitude coordinates. In this latitude and longitude lesson, students locate points on a grid and learn how to use an astrolabe.
Curated OER
Aborigine Dot Turtles
First graders create Aboriginal Dot Turtles using wax colors or crayons. The class discusses Aboriginal stories and art as a way to practice design. This lesson can be done in two 30-minute lesson segments.

Curated OER
Due Process: Is It Always Due?
Students explore the basic Constitutional protections of due process and then consider the balance of these basic protections with issues of national security. A variety of segments of U.S. Supreme Court cases are examined in this lesson.
Curated OER
COULD YOU START A BUSINESS?
Students learn how a business starts and finds financial independence. In this instructional activity, students learn the struggle of financial management, the costs of running a business and how to keep a budget.
Curated OER
Spatial Relationships
High schoolers investigate the geometry concept of spatial relationships. They draw a replica of a cube. Students list the planes on the cube and go into further depth with identifying the parallel line in segments of the cube. The...
Curated OER
Slope Fields
Students sketch a slope field for a given differential equation, given a slope field. They also match a slope field to a differential equation and match a slope field to a solution of a differential equation. Finally, students use a...
