Curated OER
Measuring the Earth
Young scholars identify types of arcs and angles in a circle, find the measure of arcs and angles, and solve real world problems involving lengths of segments in circles, lengths, and areas.
Curated OER
Infinite Secrets
Students duplicate the method that Archimedes used to estimate the value of pi. They complete a data table and find the approximate values of pi for three sets of polygons.
Curated OER
Using Nets to Find Surface Area
Eighth graders explore three-dimensional objects (prisms, pyramids, cylinders and cones) to draw nets. They use the understanding of drawing nets to find the surface area of pyramids and cylinders.
Curated OER
Quadrat Sampling 101
Students explore the population of grass plants in a given area. They plan and conduct a sampling activity to estimate the population of dandelions or the number of grass blades on the school grounds.
Curated OER
What Are The Characteristics of Your Neighborhood?
Students make a mental map of their neighborhood. Using a software program, they make an aerial and digital map of their school and locate their school on given maps. In groups, they calculate the distances to various locations and...
Curated OER
Geo-Town
Second graders use a checklist to construct a Geo-Town map including a compass rose, a map key, and a paragraph about a walk around Geo-Town, using appropriate geometric and directional vocabulary to identify the two-dimensional figures...
Curated OER
How Did This Happen?
Students use websites and discussion to investigate the 2004 Asian Tsunami. Students identify the Indian Ocean coastline's physical, political and human geography features and consider how they affected loss of life and property in those...
Curated OER
Investigation of Pot Sherds
Fourth graders review their prior knowledge on the concept of pi. Using broken pieces of pottery, they calculate the circumference from a section of the circle. In teams, they compete against one another to get the most accurate...
Curated OER
Investigating the properties of a circle
Students use wax paper to look at different properties of circles such as chords, tangent lines, inscribed angles, and inscribed angles in a semi-circle, as well as finding the center of the circle, and use GSP to investigate cyclic...
Curated OER
The Colors on My TV Screen
Students explore how electronic screens use only three colors to produce the colors that people see on the screen. They make and test a color wheel.
Curated OER
Polygons and Angles
Sixth graders estimate the measurement of angles and then measure the exact distance using an angle ruler. In groups, they explore shapes and recognize the characteristics acute, obtuse and right angles. Students sketch required shapes,...

Learners experiment with rearranging shapes to better visualize the Congruence and relationship of geometric shapes.
Curated OER
"it's All in the Cellar"
Seventh graders examine the process of constructing a site plan map at archaeological sites. They discuss the process of mapping techniques and calculation of percentages, create a plan site map of a cellar at Jamestown, and calculate...
Curated OER
What a Site!
Fourth graders are introduced to how to properly create a grid site. In groups, they use Cartesian coordinates to establish the boundaries for the grid and photograph the location of artifacts. They exchange their photos with another...
Curated OER
Build and Test
Students display what they have learned about bridges as they construct their bridge. They present their projects to the rest of the class. They compare and contrast the construction of the bridges.
Curated OER
Deer Tracks
Young scholars use satellite images to track to movement patterns of deer and examine deer behavior. They write stories about a day in the life of a field scientist.
Curated OER
Hexagoning the Circle
Students explore similarity to see that the area of a circle should be a constant times the square of its radius. Students create a hexagon. Students share their designs with the class.
Curated OER
Sunshine and Shadows
Students measure their shadows early in the morning, record direction of shadow, make marks in ground with chalk or tape, measure with ruler, and record results. Students repeat process at noon, and then later in afternoon. Students...
Curated OER
And Around We Go!
Sixth graders conduct a survey and collect data to construct a bar graph that will then be changed into a circle graph. With the bar graph, 6th graders compare estimated fractions and percentages and estimate percentages. With the circle...
Curated OER
Our Solar System to Scale
Students calculate the diameter of planets and their relative distances. In this space science lesson, students discover how small or big the planets are in comparison to each other. Students use cross multiplying fractions to find the...
