Lesson Notes
  • Pose the question: "How big is your bed?" Ask: How should we answer this question? Should we tell how long my bed is?
  • Children talk about these questions before marking 'Yes' or 'No' to the question 'Should I tell how long my bed is?'' Repeat for each of the other questions on the worksheet.
  • Look back at each of the 'Yes' responses and discuss ideas and materials that every child could use to make each measure of length (width, height). Examples might include: Hand-spans, feet, straws, popsticks...
  • Children may also decide to measure the weight of their bed by hefting (lifting one or more ends) and comparing to other objects such as: "My bed is heavier than my school bag." "My bed is too heavy for me to lift." "I can only lift a corner of my bed as it is too big and too heavy"....
  • Children use pictures, words and numbers to describe their lunchbox size.
  • Share findings
ReflectionsAsk: How are all beds alike? How are they different?
