Mathematics
Mathematics in KTET Paper I covers content up to Class V plus the pedagogy of how children build mathematical ideas - the exam favours reasoning over speed.
Content anchors
- Number: counting, place value (ones to thousands), Indian and international numeration, rounding, factors and multiples, HCF and LCM by listing, primes up to 100.
- Operations: the four operations with regrouping; one- and two-step word problems; estimation to check answers.
- Fractions and decimals: proper, improper and mixed fractions; equivalence and comparison; addition and subtraction with like and unlike denominators; decimals to hundredths.
- Geometry and measurement: 2D and 3D shapes, symmetry, perimeter versus area, standard units (cm, m, km; g, kg; mL, L), time and money.
- Data handling: pictographs with a scale, tally marks, bar graphs.
Pedagogy that is examined
- Concrete, pictorial, abstract (CPA) sequence; Classes I–V learners are largely at Piaget's concrete operational stage.
- Van Hiele levels: visualisation, then analysis, then informal deduction.
- Error analysis: a wrong answer is diagnostic information, not noise.
Worked example
A child writes 3/4 ÷ 1/2 = 3/8. Reasoning: he has applied the multiplication rule - multiply numerators, multiply denominators - to a division problem. Correct procedure: keep 3/4, change ÷ to ×, invert 1/2, so 3/4 × 2/1 = 6/4 = 1 1/2. Check by meaning: how many halves fit into three-quarters? One and a half. Teaching move: fold paper or use fraction strips so the inversion rule is seen, not memorised.
Traps that cost marks
- Confusing perimeter (boundary, in cm) with area (surface, in cm²).
- Treating place value as column labels instead of a 10-for-1 exchange.
- Giving the rule before the model, so the child computes but cannot reason.
