Mathematics and Environmental Studies (Lower Primary) / Mathematics and Science or Social Studies (Upper Primary)
Two 30-mark sections
Paper I has Mathematics (30) and Environmental Studies (30). Mathematics covers numbers to four digits, the four operations, fractions, shapes, measurement, time, money, patterns and simple data. EVS draws on family, food, water, shelter, travel, plants, animals and Assam's local environment. At Upper Primary the same area splits into Mathematics with Science, or Social Studies, with deeper content.
Maths anchors
- Place value using bundles of ten and the number line; expanded form.
- Operations with regrouping; read word problems for the exact question asked.
- Fractions as equal parts of a whole or of a set; halves and quarters.
- Perimeter and area of rectangles; units cm, m, kg, g, litre, ml.
- Time to the minute; money in rupees and paise.
EVS anchors
- Insects have six legs and three body parts, so a spider is not an insect.
- Assam context: the Brahmaputra, Kaziranga and the one-horned rhinoceros, tea gardens, Magh Bihu, bamboo and cane craft.
- Health, safety, water conservation, festivals and community life.
Worked example
A field is 15 m long and 10 m wide. A boy runs twice around it. How far does he run?
He covers the boundary: 2 × (15 + 10) = 50 m once, so 100 m for two rounds. Area, 150 m², is the trap - it measures surface, not the distance around.
Traps
Convert units before calculating; distinguish how many more from how many altogether; never use area for fencing. In EVS, a bat is a mammal, not a bird, and a whale is not a fish.
