  • Measurement involves using consistent units in order to make comparisons 
  • Estimation is an important aid in measurement skills 
  • Area, Perimeter and Volume are related to each other

Inquiry Question

How might we use linear measurement in our world?

Resource

Learner to create their own measuring device and explain how it works with examples of items they have measured in their home. Encourage learner to upload images/videos of their measuring device design to share and discuss with their peers. Reflect on what aspects are important for a measuring device.

Provide the learner with a 1 metre piece of tape (unmarked). Invite learners to work out how many cm’s there are in a metre. 

ABC Splash

ABC Splash website. A video, High Rise Living, explains linear measurement. Activity: The video states the average Year 3 student is 132cm and the average mum is 161cm, is this true in your home?

Australian Curriculum Lessons

Australian Curriculum Lessons website provides learning inquiries aligned to the Australian Curriculum. The investigation, Exploring Length, provides students the opportunity to apply their understanding of centimetres and metres in a range of hands on learning activities. Additionally, it introduces students to estimating, comparing and ordering as important skills of measurement.

re(Solve)

re(Solve) is a Mathematics and Numeracy website with many inquiries aligned to the Australian curriculum. This link, Measurement: Jump develops students’ skills in measuring metres and centimetres. It also develops students’ appreciation for distance as they make estimates and compile and compare data from experiments.

Top Model

Top Model: Challenge learners to create a fashion top for a family member out of newspaper. Ensure they measure all required parts to get the perfect fit. Have learners upload and share their design.

Teacher Advice:

When teaching measurement concepts ensure students can distinguish between going about the measuring process and conceptually understands what they are doing when they measure. When students are exploring concepts of measuring encourage them to: 

  • Make comparisons
  • Use models of units 
  • Make and use measuring instruments 
  • Move from informal to standard units 
  • Estimate and approximate

Considerations and strategies for EAL Learners 

Metric units use common morphemes to make new words (for example ‘cent’, ‘kilo’). These morphemes play an important role in helping to comprehend words and spell them. Morphological knowledge is crucial for EAL/D students, as it allows them to efficiently expand their vocabulary, through building word families.  Unpack the meaning of words (for example centi = 100, metre = to count; kilo = 1000, kilometre, kilogram, kilowatt). 

The language of comparison in English includes the use of the comparative adjective forms. These include: adding ‘–er’ to one– or two–syllable adjectives – ‘This square is smaller’, using ‘more’ for adjectives with more than two syllables – ‘The circle is more difficult to split’, and adding ‘the’ and ‘–est’ to form the superlative – ‘This rectangle is the biggest.’ Explain different forms of comparative adjectives in the context of student learning. Build lists of comparative and superlative forms, with the words in context.
