Curated OER
Polydron Fun
Young scholars investigate nets as they relate to volume and area. In this geometry lesson, students use nets as a visual to deepen their understanding of surface area and volume of objects. They make conjectures about different objects...
Curated OER
Shape Makers
Classify and explore shapes by giving learners opportunities to handle, describe and classify 2D and 3D shapes. Primary learners will sort objects such as triangles, squares, oblongs, circles, ovals, pentagons, hexagons, diamonds, boxes,...
Curated OER
Strongest Polygon
Students define and identify shapes by name. In this geometry lesson plan, students construct, identify and compare polygons based on the number of sides. They classify each shape based on their angle sum theorem.
Curated OER
Squares to Compare
Young scholars investigate how to draw and classify two and three dimensional figures (squares, triangles, rectangles.)
Curated OER
Marshmallow Figures
Students enjoy making 3-D figures while learning about rectangular prisms, pyramids, vertices, edges, and faces. After a lecture/demo, students use marshmallows, toothpicks and a worksheet imbedded in this lesson to create 3 dimensional...
Curated OER
What a View!
Students examine two- and three-dimensional shapes and figures. Individually, they practice identifying the shape from various viewpoints. By completing this activity, they develop a spatial sense about how figures and shapes are...
Curated OER
3-D Attributes
Students explore geometric solids. In this geometry instructional activity, students listen to the book The Greedy Triangle by Marilyn Burns, then work in groups to sort geometric solids into various categories. Students define geometric...
Curated OER
Seeing Seeds
Learners identify different types of seeds and label the outside and inside of a seed. Students create their own model of a bean seed.
Curated OER
San Diego Architecture
Eighth graders study the cultural and architectural history of San Diego. After study they create a design of a home based of features from historical and modern homes found in their research.
