What is “Shapes Around Us” in Class 4 Maths?
In CBSE Class 4 Mathematics, “Shapes Around Us” introduces young learners to spatial reasoning and the geometry of the physical world. Rather than just memorising formulas, children explore:
🧊 3D Solids
Cubes, cuboids, cylinders, cones, and spheres with their faces, edges, and corners.
🏛️ Prisms & Pyramids
Understanding shapes with two parallel polygon bases versus shapes rising to a single apex point.
📦 2D Nets & Folding
Unfolding 3D boxes into 2D flat patterns and visualizing how they fold back up.
📐 Angles When Lines Meet
Identifying Acute (< 90°), Right (exact 90° 'L' corner), and Obtuse (> 90°) angles.
⭕ Circles & Diameter
Discovering Centre, Radius (r), and why the full crease Diameter is always 2 × Radius.
🔺 Shape Rigidity & Puzzles
Why triangles never deform when pushed (used in bridges) and solving matchstick puzzles.

Look at the L-shaped cube arrangement below: The bottom base layer has 3 cubes in a line, and the top layer has 2 cubes stacked directly above. How many total cubes are in this shape?
👆 Tap cubes to count
Total: 5 cubes
Tap each cube to count it • Bottom row (3) + Top row (2) = 5 cubes
Q13 of 40🧱 Cubes and Cube TowersINTERMEDIATE
+25 XP
Six concrete unit cubes form a 3-step staircase (1 cube on step 1, 2 cubes in column 2, 3 cubes in column 3). If each cube has 6 faces (36 total faces), how many faces are NOT visible from the outside?
👆 Tap cubes to count
6 cubes × 6 faces each = 36 total faces
Visible (front + top + side) = 12 faces
Hidden faces = 36 − 12 = 24 faces
