Measurement can develop in the earliest years from children's experience and it readily lends itself to real-world application. Focusing on research and practise, NCTM's 2003 yearbook presents current thinking about the learning and teaching of measurement, including students' understanding, the mathematics of measurement, estimation and approximation, connections and pedagogy. The companion booklet, which not only illustrates some of the issues from the yearbook but also contains activities that go beyond the content, contains teaching notes and ready-to-use handouts.
