Measurement scales with whole numbers

New Zealand Curriculum: Level 2-3

Learning Progression Frameworks: Measurement sense, Signpost 4 to Signpost 5

Target students

These activities are intended for students who can apply their understanding of whole number place value with two-, and possibly three- digit numbers. By the beginning of Level 3 students are expected to use scales, such as a ruler, to measure the length of objects using appropriate metric units. They are also expected to solve problems in which metric units and combined or partitioned. Students are developing an understanding of choosing an appropriate degree of precision for a measuring task. They are also learning to estimate measures where the divisions on the scale do not align with the object being measured.

The following diagnostic questions indicate students’ understanding of, and ability to use, linear scales to measure length. (show diagnostic questions)
