Applied Science - Science and Math Lab
Students investigate topology. In this Applied Science lesson plan students explore higher, more abstract mathematics using tangles. Students make topologically related shapes.
Curated OER
3-D Figures Part 2
Young scholars work with three dimensional objects. In this geometry instructional activity, students examine models of spheres, cones, cubes, prisms, and pyramids, and identify them by their edges, vertices, and faces.
Curated OER
What's in the Bag?
Help your students identify the attributes of two-dimensional shapes. They read the book Round is a Mooncake, and use pattern blocks to sort shapes. Students sort shapes according to their attributes.
Curated OER
Space and Shape in Geometry:
Students are asked to visualize three-dimensional figures and apply this visualization to problem solving.
Curated OER
Pyramids with Basic Bases
Students explore pyramids. In this math lesson, students discuss where they have seen examples of pyramids. Students classify pyramids as three-dimensional figures and identify their attributes.
Curated OER
Present Hunt
Students identify and match pictures of three dimensional shapes while playing a board game with peers. They take turns with their partners in spinning the spinner and moving to the next space on the game board that shows the same shape.
Curated OER
Three-Dimensional Figures
Sixth graders explore three-dimensional objects. In groups, they create and decorate their own polyhedron design. After identifying the faces, vertices, and edges of the polyhedron, 6th graders determine a relationship between the...
Curated OER
3-D Figures Part 1
Elementary schoolers explore 3-D shapes. They transition from thinking of shapes as only 2-D. Pupils read Cinderella as a launching activity for their upcoming adventure, and explore a new world of 3-D shapes in this introductory lesson.
Curated OER
Geo Jammin' - Day 2, Lesson 4: Sing a Song of Shapes
Students learn five songs to define and develop understanding of the attributes of two- and three-dimensional figures and the meaning of mathematical terms. They classify objects as either two- or three-dimensional, through the use of...
Curated OER
Squares to Compare
Students investigate how to draw and classify two and three dimensional figures (squares, triangles, rectangles.)
