Curated OER
Mapping a Site Using a Coordinate Plane
Learners map their playground as if it were an archeological site. They locate objects on the playground and determine their location using coordinate points. A related instructional activity is Coordinate Grid: Mapping an Archeological...
Curated OER
Coordinate Geometry
Grab your class and get them graphing polygons on a coordinate plane! They investigate the four quadrants, discover the x and y axis, and correctly plot ordered pairs. To show their comprehension, each child creates a coordinate picture...

Creating a Reflection
Investigate geometric reflections in this geometry lesson. Create geometric reflections that show the reflection across the x and y axis of a coordinate graph. Learners watch a teacher demonstration before proceeding on their own. They...
Curated OER
Tessellations
Students learn and review basic geometric terms, definitions, and theory, including regular polygons, lines, angles, points, etc. They make a tessellating stamp and create a repeating work of art.
Curated OER
Estimation, Sampling, and Beyond
Students examine an ISS EarthKAM image of farm land in Texas and New Mexico. They select sample region of image and count the number of fields in that region. They estimate how many fields are in the entire region.
