ICSE Class 6 Maths, Unit 5: Mensuration
From the CISCE curriculum. 6 key concepts, about 3 days of study at 20 to 30 minutes a day.
What this unit aims at
In the previous three classes children were learning the measurement of various quantities like length, mass, temperature and time. Mathematically proficient students communicate precisely by engaging in discussion about their reasoning using appropriate mathematical language. The terms students should learn to use with increasing precision are area, surface area, volume, decomposing, edges, dimensions, net, vertices, face, base, height, trapezoid, isosceles, right triangle, quadrilateral, rectangles, squares, parallelograms, trapezoids, rhombi, kites, right rectangular prism, and diagonal. Children continue to strengthen their understanding that area is the number of squares needed to cover a plane figure. Thy will also know the formulas for rectangles and triangles. “Knowing the formula” does not mean memorization of the formula but to have an understanding of why the formula works and
Your child should be able to
- describe the concept of perimeter of various shapes
- demonstrate the idea of area and volume of shapes
- calculate the perimeter of different shapes given, she tries to formulate the perimeter of shapes like rectangle, square
- calculate the areas of rectangle ad square by dividing them into appropriate smaller units. she tries to think of such small units
- use conversion of units of mass, money, time, and capacity in different daily life situations
Key concepts in this unit
- Concept of perimeter and introduction to area Introduction and general understanding of perimeter using many shapes.
- Shapes of different kinds with the same perimeter.
- Concept of area, Area of a rectangle and a square
- Conversion of units (Mass, time, money, and capacity) from to smaller to larger and vice-versa Counter examples to different misconceptions related to perimeter and area.
- Perimeter of a rectangle – and its special case – a square.
- Deducing the formula of the perimeter for a rectangle and then a square through pattern and generalisation.
Teach this unit at home
- A day-by-day plan from the CISCE concepts, so you know what to cover each day.
- A step-by-step script for each day, so you know what to say and ask (AI-written from the CISCE curriculum, so check it against your child's school book).
- A quiz at the end.
