Question

Quizplus · Accepted Answer

Referents, also known as benchmarks or comparisons, help students make reasonable estimates by providing a context for their estimation. For example, estimating the height of a tree by comparing it to the height of a nearby building or using a known weight to estimate the weight of an unfamiliar object. Using small numbers or heuristics may also be helpful in some cases, but comparisons are the most reliable and consistent referents for estimating.
