The Standard

Solve real-world and mathematical problems involving area, volume and surface area of two- and three-dimensional objects composed of triangles, quadrilaterals and polygons including cubes, right prisms, and pyramids.

What This Standard Means

What Students Need to Do: Students find the area of flat shapes made from triangles and other polygons. They split combined shapes into simpler parts, then find area, volume, or surface area from the given lengths.
What Mastery Looks Like: Students show how they split a shape and combine the results correctly. They use the vertical height for a pyramid’s volume and count only outside faces when finding the surface area of joined solids. They label answers in square or cubic units.
Common Misconceptions: Students may use slant height instead of vertical height for pyramid volume. They may count hidden faces where solids join or label volume in square units.
How to Assess It: Exit ticket: Draw a square pyramid with 6 cm base edges, a 4 cm vertical height, and a 5 cm slant height. Find its volume and total surface area, and label the height used for each.

Ways to Teach It

Cut and fold a square pyramid net with a 6 cm base and four triangles with 5 cm heights, then find its surface area.
Draw a 6 cm by 4 cm rectangle with a 2 cm by 3 cm corner removed, then explain how you find the remaining area.
Match prism and pyramid cards with 4 cm by 3 cm bases and 6 cm heights to volume cards, showing calculations.
Measure a cereal box, calculate the area of its six faces, then compare that measurement with its volume.
