Learning Intention:
  • Students explore size through direct comparison

I Can:
  • Compare the weight of two objects directly
  • Describe the size of an object in relation to another object using comparative language (heavier, lighter, equal)
  • Describe the size of an object in relation to a purpose or need, using comparative language

Together we had a group discussion about the words WEIGH and WEIGHT. Some of the guiding questions were: Have you ever heard these words? What do these words mean? Can you give an example?  Students came up with the following:
  • "It means how much something weighs - like how heavy it is."
  • "I weigh myself at home on a scale."
  • "At my doctor's I stand on a scale and they see how much I weigh"
  • "People weigh food because I've seen them do it at Superstore."

Next students worked in groups and were given a variety of classroom objects to explore and talk about using comparative language such as heavy/light, heavier/lighter/ heaviest/lightest as well as equal/balanced. Students did a great job working together in their groups sharing the objects as well as thinking and conversing like mathematicians as they discussed their discoveries about the different weights of each object.
