Isometric drawing of cubes and cuboids

Isometric paper turns a 3D box into a flat drawing you can read. Three faces show at once and every edge keeps its length — so you can draw a cube and count the unit cubes inside a cuboid.

Kavi Draws in 3D 🧊

Kavi props an ice cube on the branch and tries to draw it flat. On square paper it keeps looking squashed! "Try isometric paper," Kavi hoots. "Its lines make little triangles, so the box stands up on the page — you can see three faces at once and every edge is drawn the same length. Now I can draw a cube and count the little cubes inside a big one."

What your child will learn

1A cube on isometric paperIsometric paper lets you draw a solid so it still looks 3D on a flat page. Its grid is made of triangles, not squares. Tap each part to see how a cube is built on it.

2Draw a cube, step by stepA cube is easy once you work in order. Kavi always starts with one vertical edge, then builds outward along the grid lines.

3Cube or cuboid? Read the edgesA cube and a cuboid are both drawn the same way on isometric paper. To tell them apart, read how many cubes long each edge is. Tap each card.

A peek inside

Kavi draws a cuboid on isometric paper: it is 2 cubes long, 3 wide and 2 high. How many unit cubes is it made of?

count the cubes layer by layer — length × width × height = 2 × 3 × 2

Try this at home: On isometric paper, how many faces of a cube can you see at once?
