Subject Content (Language / Mathematics / Science / Social Science)
What the subject-content section demands
The Subject Content part of the LTR Teacher exam is set at the level of the subject and classes (VI–VIII) you opt for. It blends content knowledge with content-cum-methodology: you must solve a problem correctly and show that you know how it is taught. For Mathematics, expect number system, ratio and proportion, percentage, algebra, geometry, mensuration, and data handling. For Science, expect laws, SI units, human body systems, and Odisha-relevant environment. For Social Science, expect Odisha history, Indian polity, and basic geography. For Language, expect grammar, comprehension, and composition.
Core rules and concepts
- Mathematics: percentage change is multiplicative, not additive; in ratio problems, keep the same unit; area and volume units must match.
- Science: mass is constant, weight changes with gravity; SI units (N, J, W, Pa) must be written correctly.
- Social Science: link Odisha dynasties to their inscriptions and monuments; link constitutional articles to rights and duties.
- Language: identify sandhi and samasa by the operation, not by memorised labels.
Worked example
A shopkeeper marks an article at ₹800 and offers two successive discounts of 10% and 5%. Find the selling price. Reasoning: after 10%, price = 800 × 0.90 = ₹720. After 5%, price = 720 × 0.95 = ₹684. The equivalent single discount is 1 − (684/800) = 14.5%, not 15%. Adding 10% + 5% is the trap; successive discounts are applied to the reduced price.
Traps that cost marks
Do not add successive percentages; do not mix cm² and m² without conversion; do not confuse mass and weight; do not treat Kalinga and Kosala as the same region; in language items, do not choose a sandhi name before checking the actual vowel change.
