LIDAR: Mapping with Lasers
We would be lost without maps! How are they made? Introduce junior topographers to LIDAR technology with a fascinating activity. Set up a mock city, then have learners operate a laser measure to determine the shape of the landscape using...
Curated OER
Triangle Exploration
Students are introduced to The Geometer's Sketchpad software while in the computer lab. They focus on triangles, horizontal lines, vertex and top parallel lines. Each student utilizes geometry to complete basic geometric constructions.
Curated OER
Introduction to Slope
Students distinguish between positive and negative slope. They calculate the slope of various lines. Students identify and generate perpendicular and parallel lines base on their slope.
Curated OER
Angle Pairs
Students identify different angle pairs. In this geometry lesson, students identify the different angles of two parallel lines cut by a transversal. They identify the interior and exterior angles.
