Basic Geometry & Shapes: Solids, Angles and Circles - Class 4 Maths Worksheet
Count the edges, faces and corners of prisms and pyramids, tell acute, right and obtuse angles apart, use the radius and diameter of the centre circle and see why a triangle is the strongest frame.
Learning Objective
Name prisms and pyramids and count their faces, edges and corners, read a net, tell acute, right and obtuse angles apart, use radius and diameter, and know that a triangle is a rigid shape.

- Boot Box Corners: Look at the boot box.
- Find the Pyramid: Tap the square pyramid.
- Prisms and Pyramids: Tap a card. Then tap its group.
- Pyramid Corners: Look at the triangular pyramid.
- Roof Rectangles: Look at the dugout roof.
- Find the Right Angle: Tap the right angle, like the corner of a pitch.
- Sort the Angles: Tap a card. Then tap its angle group.
- Goal Corner: Look at the corner where the post meets the crossbar.
- Circle Rope: Look at the rope from the centre spot.

Note for Parents & Teachers
This follows the NCERT Class 4 chapter "Shapes Around Us". A prism has two matching ends joined by rectangles; a pyramid has triangle faces that meet at one point. An angle smaller than a square corner is acute, a square corner is a right angle, and a bigger one is obtuse. The radius of a circle is half of its diameter. Football fact used: a classic football is stitched from 12 pentagon and 20 hexagon patches. At home, look for right angles in doors, books and windows.
