Standards/Essential Questions:
- 5.MD.5a RELATE volume to the operations of multiplication and addition and solve real world and mathematical problems involving volume. 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.
- 5.MD.5b APPLY the formulas V=lxwxh and V=bxh 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.
- 5.MD.5c 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.
Big Ideas:
- Volume refers to the amount of cubic units required to fill the inside of a solid figure or the amount of space that an object takes up.
- Volume is measured by finding the number of cubic units that fit within a solid figure. When measuring an edge of a rectangular prism in linear units, you are finding the number of cubic units that fit along that edge.
- Volume is measured in cubic units. As with linear and area measurements, the size of the unit should relate to the size of the solid being measured (ie. larger units are used for measuring larger spaces and vice versa).
- When finding the volume of cubes and rectangular prisms the area of the base is multiplied by the number of layers (Height) in the prism. This could also be found by l x w x h (length x width x height)
