1.
− The use of non-standard units allows individuals to focus directly on the attribute
being measured.
− For people who are familiar with a non-standard unit they may be better able to
understand it. If I said someone was as tall as my chin, then anyone who knew me
would know what I meant and would be able to visualise the other person's height.
− Non-Standard Measurement is a way of introducing Pre School or grade 1 learners
to measurement. It involves finding out how big, heavy, long something is and how
two or more objects can be directly compared to each other. Non-Standard
measuring is the foundation of real measurement. Without it, students do not
understand the more complex concepts.
2.
− Estimation refers to a mental picture or idea that a person uses to make a
measurement of an object or make a comparison without using any measuring
instrument.
− Practical skills are used on daily for estimation. For example: Will my car fit into the
parking?
− Estimation helps learners focus on the thing being measured and think about which
unit can be used.
− For learners to understand measurement concepts, they should start by making an
estimation. This goes for both non-standard and standard units.
3.
− Begin the lesson by asking the students if anyone has a fenced garden and ask them
to think about how you might figure out how much fencing was needed.
− Let the students know what they will be doing and learning today.
− Have the class measure the perimeter of their book using their eraser as the non-
standard unit of measurement.
− Discuss the different answers the students calculated and why the answers differed.
− Introduce the term perimeter.
