Figure Weights

20

How this works

Each problem shows one or more balance scales. Every scale shown is perfectly balanced — the shapes on the left weigh exactly the same as the shapes on the right.

The last scale has a question mark on one side. Use the balanced scales as clues to figure out which set of shapes would balance it, then choose from the options below.

Rules of thumb: Shape weights are consistent within a problem but change between problems. Each item is timed — 20 seconds for early items, 30 for later ones. If time runs out, the test moves on.

You'll start with one untimed practice problem.

Informal analogue of the WAIS-IV Figure Weights subtest for instructional and demonstration purposes. It is not a normed or standardized instrument and yields no scaled scores. Tiers: Matching (1–3), One-scale substitution (4–7), Two-scale chains (8–11), Multi-scale reasoning (12–15).
