4.GM.1.3

4.GM.1.3 Given two three-dimensional shapes, identify the shapes. Compare and contrast their similarities and differences based on their attributes.

In a Nutshell

This objective requires students to use their knowledge of the attributes of three-dimensional shapes (e.g. cubes, rectangular prisms, and pyramids) to compare two three-dimensional shapes. To do this successfully, they must identify shared and unique characteristics; including analysis of faces, vertices, and edges.

Student Actions	Teacher Actions
Develop the ability to communicate mathematically by sharing their observations with peers, developing arguments to convince peers their comparisons are accurate, and discussing and critiquing the arguments of others. Develop mathematical reasoning by comparing two three-dimensional objects, identifying shared and unique characteristics, and recording these observations in a Venn diagram or other graphic organizer. These observations should include the use of appropriate mathematical language and terms (faces, vertices, edges, etc.)	Facilitate meaningful mathematical discourse among students by encouraging students to analyze and compare various approaches and arguments in regard to the comparison of three-dimensional shapes. Pose purposeful questions in regard to three-dimensional shapes which go beyond simple identification and focus on the properties of the figures.
Key Understandings	Misconceptions
Three-dimensional figures can be discussed and compared based on identifying and analyzing their faces, vertices, and edges.	The terms “square” and “cube” are interchangeable labels for the same figure. If a figure is very flat, such as a sheet of paper, it is not 3-dimensional. Faces, edges, and vertices are the same, or a figure will have the same quantity of each characteristic.

Sample Assessment Items
The Oklahoma State Department of Education is releasing sample assessment items to illustrate how state assessments might be designed to measure specific learning standards/objectives. These examples are intended to provide teachers and students with a clearer understanding of how the state assesses Oklahoma's academic standards and their objectives. It is important to note that these sample items are not intended to be used for diagnostic or predictive purposes. Ways to incorporate the items. 4.GM.1.3 Compare and Contrast
