What it is

An architect's studio in 3D. Count cubes in buildings (some are hiding!), build boxes to an exact volume, follow front, side and top drawings, pick the net that folds into a cube, and design solids with a target surface area. Any building that meets the plan is correct.

What children learn

Volume as counting unit cubes and multiplying length × width × height; reading plans and elevations; nets and how faces fold into solids; and surface area as the number of exposed square faces.

What it teaches

  • Surface area from faces and nets
  • 3D shapes and views
  • Volume with unit cubes

How to play

Tap the floor or a stack to add a cube, or switch to Remove. Drag to turn, pinch or + and − to zoom. Keyboard: arrow keys turn the view, + and − zoom, R resets; on the build pad, arrow keys move, Enter adds and Delete removes. Choices and number answers use large buttons. A flat build pad works without 3D graphics.

Plays with: Touch Mouse Keyboard Pen
