Big Ideas: Relationships exist between two- and three-dimensional figures, such as: 2-dimensional nets can be folded into 3-dimensional figures and geometric solids have faces that are 2-dimensional shapes. The area of a face of a geometric solid is measured in square units while its volume is measured in cubic units. Pyramids and prisms can be differentiated by the number of bases and the shapes of their faces. In this lesson, students build on their understanding of geometric solids as figures that have length, width, and height. In this task, students cut out nets and fold them into 5 different geometric solids (prisms and pyramids that have rectangular and/or triangular faces). They then identify, describe, and categorize the figures. This lesson builds toward students' work in sixth and seventh grade on finding surface area of three-dimensional objects composed of triangles, quadrilaterals, and polygons. Vocabulary: 2-dimensional shape, 3-dimensional figure, apex, area, cube, cubic units, face, geometric solid, net, polygon, prism, pyramid, quadrilateral, rectangular prism, square pyramid, square units, triangular prism, triangular pyramid, volume Special Materials: Handout of nets, included in Supplementary Materials (ideally printed on card stock or index paper, 1 copy per small group of students to reduce time cutting and folding) Scissors Tape (optional)
