Class 5 Maths - CBSE
Grandmother's Quilt
The chapter 'Grandmother's Quilt' in Class 5 CBSE Mathematics introduces young learners to the practical world of spatial patterns, symmetry, area, and fractions through the colorful context of making a quilt. Students learn how to break down complex shapes into smaller unit squares, calculate the total area and perimeter of rectangular designs, and identify repeating patterns and symmetry in cloth pieces. This chapter is very important for CBSE board exams as it lays the foundational block for geometry, measurement, and fractional parts of a whole, frequently appearing in both objective and short-answer questions.

Area of a Rectangle
The amount of space occupied by a flat rectangular surface, calculated by multiplying its length by its breadth.
Perimeter
The total distance around the outer boundary of a closed shape, found by adding the lengths of all its sides.
Symmetry
A property where a shape looks identical to its other half when divided by a line of symmetry.
Fractional Parts
Representing a smaller piece of a quilt as a part of the whole, such as 1 out of 4 equal squares being 1/4.
Tessellation and Patterns
Repeating shapes in a specific order to cover a surface completely without any gaps or overlaps.

Board Exam Info
In the CBSE Class 5 Mathematics assessments, this chapter typically carries around 4 to 6 marks. Common question types include finding the area and perimeter of grid-based quilt designs, identifying lines of symmetry in colorful fabric patterns, and expressing shaded portions of a quilt as fractions.
Frequently Asked Questions
How do I find the area of a quilt drawn on a square grid?
You can simply count the total number of unit squares inside the boundary of the quilt design.
What is the difference between area and perimeter in quilt designs?
Area measures the total flat cloth space inside the quilt, while perimeter measures the total length of the border tape needed around it.
How can I check if a quilt pattern is symmetrical?
Fold the pattern along a line; if both halves match each other completely with no overlapping edges, it is symmetrical.
