Mathematics - PSTET Paper 1
Mathematics in PSTET Paper 1 tests number sense, operations, fractions, measurement, geometry, patterns, and primary mathematics pedagogy.
Number and operations
Place value underlies regrouping. Addition and subtraction should be modelled with bundles of ten and ones; multiplication as repeated addition and arrays; division as sharing and grouping. Mental math and estimation support reasonableness.
Fractions and measurement
Fractions as part-whole, equivalent fractions, and comparison need concrete strips or circles. Measurement includes length, mass, capacity, time, and money, with unit conversion. Perimeter is boundary length; area is surface covered.
Geometry and patterns
Identify 2D and 3D shapes by properties, symmetry, and spatial reasoning. Patterns extend by a rule, not by guessing the next shape.
Pedagogy
Move from concrete to representational to abstract; use manipulatives; analyse errors; teach problem-solving with understanding rather than keywords.
Worked example: A child writes 47 + 28 = 615 by adding each column without regrouping. Using bundles: 47 is 4 tens and 7 ones; 28 is 2 tens and 8 ones. 7 + 8 = 15 ones = 1 ten and 5 ones; 4 + 2 + 1 = 7 tens; the answer is 75.
Traps: teaching borrowing as smaller-from-larger; keyword-only word problems; confusing perimeter and area; dropping units; drilling the algorithm before place value.
