Triangle Area Patterns
Combine algebraic and geometric strategies to find solutions. The task asks learners to find the coordinates of a third vertex of a triangle to create a triangle with a specific area. The project is a set of seven problems that...
Math by Design
Transformations – Reflections
Scholars use interactive resources to figure out how to mathematically draw a reflection of a geometric shape viewed in a mirror. To conclude the activity, class members are asked to deduce the result of multiple reflections across...

Mapping with a Compass: A Simulated Survey
Students use compasses and grids to map the locations of artifacts found in a simulated dig site. In groups, they role-play as future archeologists excavating a school site. Groups begin at their assigned datum and site the artifacts...
Curated OER
Maps, Charts, and Graphs
Students define key geographic terms and track a hurricane on a map. They examine various types of maps and find locations on them,including rivers, cities and mountains.
Curated OER
Three D Constellations
Students are introduced to both celestial coordinates and to the first rung on the distance determination ladder. They convert spherical coordinates to Cartesian coordinates to construct a three dimensional model of a constellation...
Curated OER
Graphing Ordered Pairs
In this graphing ordered pairs activity, 9th graders graph five different sets of numbers on five different graphs. They identify that each of the x-coordinates tells the distance right (positive) or left (negative) and that each...

Quadrilateral Explorations
Ninth graders identify quadrilaterals and label the vertices of quadrilaterals. they justify their identification of the quadrilaterals. Students work in groups to identify and create quadrilaterals
Curated OER
Seasons
Students investigate the reason for seasons on Earth during three activities. They construct a model of the Earth and Sun to identify patterns in the changes of the angle of light on the Earth's surface. Then they conduct a heat...
Curated OER
The Earth is Flat
Third graders experiment to gain understanding of the shape and rotation of the Earth. In this Sun and Moon science lesson, 3rd graders understand that the Earth rotates on its axis and how that explains the appearance of the moon and sun.
