Purpose and Instructional Strategies

The purpose of this benchmark is to begin formal categorization of three-dimensional figures based on attributes of their faces, edges and vertices. Three-dimensional figures were identified informally in Kindergarten and grade 1. The work in grade 5 prepares students for more detailed work with three-dimensional figures, including finding volumes and surface areas using formulas and nets in grade 6 (MA.6.GR.2.4). 
  • Instruction includes having students use language they have already learned and apply it to a larger variety of figures including prisms and pyramids with any number of sides. 
  • Instruction includes explaining that a cone has one flat base, a cylinder has two flat bases and a sphere does not have any flat bases, but each of these figures has a curved surface.

 

Common Misconceptions or Errors

  • Students may believe that the orientation of a figure changes the three-dimensional shape.

 

Strategies to Support Tiered Instruction

  • Instruction includes teacher providing a graphic organizer that contains three-dimensional figure names and definitions from the glossary. Students match images of the figures in different orientations to their definitions. 
    • For example, the teacher provides students with a graphic organizer like the one shown below and a set of three-dimensional figure picture cards. Students match the image to the defining attributes listed. 

  • Instruction includes providing three-dimensional figures made of plastic or wood and having students identify the shapes that make up their base or bases and faces. Students then look at the definition for each figure and classify it based on the attributes they identified. 
    • For example, the teacher provides the students with a triangular prism like the one shown below. The students then identify the two bases as triangles and the faces connecting them as rectangles. The teacher provides students with the definitions for three-dimensional figures and has them determine which classification it fits in.

Lesson Plans

Using Machine Learning and Computational Thinking to Train an AI Model:

Students will explore Artificial Intelligence (AI) and use computational thinking and Machine Learning (ML) to pretrain a model to recognize and identify objects, including geometric shapes and aircraft. They will used unplugged activities to mimic sorting and classification of the objects using their prior knowledge and then make connections to human learning and Machine Learning. Students will then problem solve and propose solutions using computational thinking to improve the ML model to better recognize the objects. This lesson is an integrated Computer Science, Science and Math lesson designed for students in grades 3-5 to apply math and science content knowledge while exploring and using computational thinking as they think like Computer Engineers and reflect on potential career paths.
