Mensuration

This CTET Paper 2 chapter builds Mensuration for future Classes VI-VIII maths teachers: SI units of length area volume; perimeter versus area; rectangle square triangle circle; parallelogram trapezium; cube cuboid cylinder cone sphere at upper-primary level; nets of solids; capacity versus volume; common formula errors; grid-paper and clay TLM; and pedagogy that diagnoses misconceptions before drill. Sibling Geometry stays a one-line contrast only; Algebra Ratio Data Handling and broad Maths pedagogy are not expanded here.
