Common Core Math
5.MD.C.5.a
Primary
Find the volume of a right rectangular prism with whole-number side lengths by packing it with unit cubes, and show that the volume is the same as would be found by multiplying the edge lengths, equivalently by multiplying the height by the area of the base. Represent threefold whole-number products as volumes, e.g., to represent the associative property of multiplication.Reason: The project involves using unit cubes to recognize volume measurement and demonstrate mathematical concepts like multiplication and associative property.
5.MD.C.5.b
Primary
Apply the formulas V = l × w × h and V = b × h for rectangular prisms to find volumes of right rectangular prisms with whole-number edge lengths in the context of solving real-world and mathematical problems.Reason: Students will learn and apply these formulas in practical contexts, directly aligning to this standard.
5.MD.C.5.c
Primary
Recognize volume as additive. Find volumes of solid figures composed of two non-overlapping right rectangular prisms by adding the volumes of the non-overlapping parts, applying this technique to solve real-world problems.Reason: The project explores decomposition of complex shapes into simpler volumes, fulfilling this standard's requirements.
