Lesson Notes
  • Children require the opportunity to freely play with and explore filling containers such as backpacks with clothes, balls 'scrunched' newspaper...
  • Provide children with a copy of activity sheet A and ask the focus questions.
  • Direct children to the activity sheet and ask: Backpacks are not all the same size. Can you draw a picture to show 3 backpacks that are different sizes?
  • Move around the class and ask: This is your big backpack. Is it higher/wider/deeper than the other backpacks? Which backpack has the most space? Least space? What might you carry in this small backpack? Where might you use the large backpack? Have you got a story about a time when you packed a backpack?
  • Place children into groups, each with a backpack and a set of dress-up clothes (or different size balls such as basketballs, tennis balls, footballs...). Direct groups to the 'Find Out' question and ask: Will all the clothes pack into the backpack? Decide as a group and then put a tick in the box to show what your group thinks.
  • Direct groups to fold/roll clothes neatly to pack them into the backpack.
  • Provide the opportunity for groups to share findings around the class.
  • Provide individual children with a copy of activity sheet B and ask the focus question.
  • Use a spider map connecting children's suggestions with the central idea - Pack for a Sleepover.
  • After all suggestions have been made and discussed ask: I want you to list all of these ideas on your activity sheet.
  • How will you make a list? How many ideas will be in your list? Does it matter which idea is first or last on your list?
  • Direct children to create their list.
ReflectionsAsk: Can others read your list of clothes? Do you think your parents would agree with your list?
