Follow one thing on paper: what you see, where it goes after a turn or a flip, where a face lands when folded. Don't turn the whole shape in your head.

Spatial Reasoning: Compass Directions

  1. 1

    Set the compass first: everything follows north

    When to use it: The question asks for a direction and something has been turned: north is not up (an upside-down map, a north arrow pointing right or left, a north arrow that really points east), or a person turns (left, right, clockwise, anticlockwise, a quarter turn, a half turn, 90°, 180°) and you must say which way they now face. It also covers reading the directions along a path of straight and diagonal lines.

    • Write the eight directions clockwise in a ring: N NE E SE S SW W NW, 45° a step.
    • Put N wherever north points and the rest follow; on an upside-down map every direction swaps to its opposite and the order stays.
    • A right turn goes clockwise round the ring and a left turn goes anticlockwise: a quarter turn is two steps, a half turn is four.
