Lesson Notes
  • Note: Regardless of whether students feel they 'know' the answer for each question they must enter an answer using a best guess or what they might imagine the answer to be.
  • Activity 1. Is a 'snowballing' activity. A 'snowballing' activity is like 'think, pair, share' except that students must AGREE on a response to each activity in the time provided.
  • Students work independently on activity 1 a-e.
  • Students work in pairs to compare answers. They must AGREE on answers in the time given.
  • The pairs then meet with another pair (group of 4) to share, and then AGREE on an answer for each situation.
  • Groups then report to the whole class to share, and justify mathematically, their responses (e.g. "I was in a plane last holidays and the pilot said we were flying at 32 000 feet." - the student justifies his/her response mathematically and with recent experience.)
  • After each group provides a response to the class listeners can be invited to ask questions of the group.
  • In activity 2 students work in small groups to determine an AGREED 'good' number for each sentence.
  • After each group provides a response to the class listeners can be invited to ask questions/debate reasonableness of solutions provided by the group.
ReflectionsAsk: Did you listen in your group and learn something new in activity 1?
