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.
