This two-week unit introduces students to the big idea ‘What you want to describe decides what unit of measure to use’. Students are provided opportunities to:
recognise that the attribute you want to describe informs the unit of measure you use
describe, compare, and order measurable attributes including length, area, volume and mass
share their thinking when working with others to solve problems.
Before engaging in these teaching and learning activities, students would benefit from prior experience with:
daily routines that focus on developing language to label attributes. For example, during bath time ‘the container is full/empty, almost full, almost empty’; when preparing fruit snacks ‘the apple is bigger than the grape, the watermelon is heavy, the cucumber is longer than the carrot’; and getting dressed ‘my socks feel lighter than my shoes’.
block play investigations that enable opportunities to communicate thinking with peers and adults who extend and narrate their play. For example, ‘the tower is tall/high’, ‘the block train/snake is longer than the mat’ and experimenting with loose items using recycled materials, ‘the small boxes/lids feel lighter than the bigger boxes’.
