Negative Numbers and Integers

This CTET Paper 2 chapter builds Negative Numbers and Integers for future Classes VI-VIII maths teachers: need for negatives when wholes fail under subtraction, the integer number line, ordering and comparison, absolute value as distance from zero, addition and subtraction with directed moves and rewrite rules, Class VII multiplication and division sign patterns lightly, minus-minus parse traps, TLM such as floor lines and two-colour counters, and misconception-aware classroom pedagogy. Sibling topics Knowing Our Numbers, Whole Numbers, Fractions, Decimals, Algebra, Ratio, Geometry, Mensuration, Data Handling and broad Maths pedagogy stay one-line contrasts only.
