Much Decimal Confusion

Today was another day in school, this morning seeing a Year 13 lesson in mechanics. They literally worked like angels and the teacher could have just done boring textbook stuff and they would have got on with it, but she still created a thoughtful lesson. In particular I noted the task for the starter, which is detailed in Task Design Observations - Amy.

Much of the rest of the day was spent interviewing Year 8 pupils about their understanding of decimals, where a variety of mahoosive misconceptions were seen:

  • tenths column is in fact the unitth column
  • 1 - 8 = 7 and 0 - 4 = 4
  • 4087 is 4 million and 87
Challenge accepted.
