Measure With Pleasure: Length Measurement Teaching Framework In Early Childhood

Table 1: Central concepts in linear measurement

Idea Description
Conceptions of unit Iteration A subdivision of a length is translated to obtain a measure.
Identical unit Each subdivision is identical.
Tiling Units fill the space.
Partition Units can be partitioned.
Additivity Measures are additive, so that a measure of 10 units can be thought of as a composition of 8 and 2, and so on.
Conceptions of scale Zero-point Any point can serve as the origin or zero-point on the scale.
Precision The choice of units in relation to the object determines the relative precision of the measure. All measurements are inherently approximate.
