Game Objective: To collect items so that the total length is equal to one metre

Materials: 1 metre ruler or tape measure

WALT: Use our knowledge of measurement to estimate length

WILF: Students use known benchmarks to help them estimate length


  • Students are put into small groups (3 – 4)
  • Each student is asked to collect one object from around the room
  • The aim is so when the objects are placed in a line their total length will be one metre
  • Students are not allowed to use rulers or other measuring tools but can choose how the objects will be positioned
  • After students are satisfied that have reached the one metre target the teacher will measure the length
  • If students are over or under, they can change one object to see if they can improve their total length (i.e. get closer to one metre)
