Class 5 Maths Chapter 7 PDF: Shapes and Patterns (Maths Mela)

Class 5 Maths Chapter 7, Shapes and Patterns, explores 2D and 3D geometry through over-and-under mat weaving, floor tiling and tessellations, 7-piece Tangram puzzles, properties of rectangles/squares/triangles/kites, compass circle designs, and polyhedra nets (cube, icosahedron, dodecahedron).

What Class 5 Mathematics Chapter 7 Covers

Weaving Mats, Tiling/Tessellation & Tangram weaves two-colour paper strips into patterned mats, tests which shapes tile (tessellate) a plane without gaps or overlaps, and combines the 7 Tangram pieces to form animals and polygons.

Properties of Quadrilaterals, Circle Designs & 3D Polyhedra identifies shapes by sides, corners and right angles (rectangles, squares, kites), draws concentric circles and radii/diameters with a compass, and folds 2D nets into 3D cubes, icosahedrons (20 triangles) and dodecahedrons (12 pentagons).

Shapes to make and test: children weave mats from paper strips, test which regular shapes fit around a point without gaps (triangles do; regular pentagons do not), sort triangles by their sides, and cut out a tangram set. They fold a square into a kite, draw circle designs with a compass, find how many small cubes are missing from cube frames, and build an icosahedron and a dodecahedron from nets, learning that the names count the faces (20 and 12).

FAQ

What is a tessellation (tiling) in geometry?
A tessellation or tiling is a pattern of flat shapes that fit together perfectly to cover a surface without any gaps or overlaps.

How is the diameter of a circle related to its radius?
The diameter passes through the centre of the circle and is exactly twice the length of the radius (Diameter = 2 × Radius).

How many faces do an icosahedron and a dodecahedron have?
An icosahedron has 20 faces and a dodecahedron has 12.
