The standard
Investigate volume of right rectangular prisms by packing them with unit cubes without gaps or overlaps. Then, determine the total volume to solve problems.
Element 5.GSR.8.3 of Georgia's K-12 Mathematics Standards (2021, effective SY2023-24), in the Geometric & Spatial Reasoning strand. It sits under standard 5.GSR.8: Examine properties of polygons and rectangular prisms, classify polygons by their properties, and discover volume of right rectangular prisms.
What students practice
Count unit cubes, connect layers to base area and height, and investigate prisms with a fixed number of cubes. Five stories and complete worked keys.
