Lesson Notes
  • Ask the first question: "is your leg longer than your arm?" Children talk about the question and provide ideas for comparing the 2 lengths.
  • Ask children to guess which is longer and complete Yes or No on the worksheet.
  • Children use materials to check their guess. Share findings.
  • Repeat for each of the 6 questions on the worksheet. In each case the children need to agree how they will make the comparisons for 'shorter', 'bigger', 'greater'.
ReflectionsDiscuss other questions that could be asked where the size of body parts is compared. Ask children to write down (or draw a picture) the question they would like to answer. Provide students with the time, space and materials to investigate their personal question.
Integration Links Writing and Speaking: Word meanings for longer, shorter, bigger, greater. Children make up other questions using these words.
