Thinking Skills study method

Use reference marks to check spatial reasoning step by step.

Instead of trying to picture every change at once, track one corner, symbol or neighbouring face through each move.

Track a feature

  1. Choose an unmistakable feature, such as a star in one corner.
  2. Describe one movement only: turn, flip, fold or slide.
  3. Check where the feature and its neighbours finish before making the next move.

Worked example

A square card has a star in its top-left corner. It is turned a quarter-turn clockwise.

A clockwise quarter-turn sends the top edge to the right edge. The star moves from top-left to top-right. Marking the star avoids confusing a rotation with a mirror reflection, which would put it at bottom-left.

A common error

Using “flip” when the diagram shows a turn. A rotation keeps the clockwise order of features; a reflection reverses that order.

Independent self-check

Before choosing an option, compare two features: the marked corner and one adjacent edge. One feature can land in the right place by chance; two checks are stronger.
