Learners explore the globe. For this globe skills lesson, students use their knowledge of latitude and longitude to respond to questions regarding Christopher Columbus's maiden voyage to the Americas.
Curated OER
Reflection
Learners examine how some transformations, such as reflections and rotations, do not change the figure itself, only its position or orientation.
Curated OER
Finding the Area of a Parallelogram with Translations
Students calculate the area of a parallelogram. In this geometry lesson, students perform translation using a coordinate plane and coordinate pairs. They perform translation on other polygons.
Curated OER
Finding the Area of a Parallelogram with Translations
Students calculate the area of parallelograms. In this geometry lesson, students identify properties of parallelograms and use to to solve problems. They create polygons using Cabri software.
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.

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
Magellan
Students identify the route of Magellan's voyage. In this map skills instructional activity, students use a globe to identify various coordinates where Magellan traveled.
Curated OER
Hang in There
Young scholars view a video clip about bridges. They examine the cables that stablize the Golden Gate Bridge. They relate this concept to elevators.
Curated OER
