decimal addition

an attempt to suggest a lesson (sequence) with sections involving
  • teaching or reviewing a skill
  • practice of that skill in tasks that involve generalisation and possibly proof
a ppt is here

for the initial task (finding change from £10 or $10) students can be taught to make the first digits up to 9 and then the last one to 10 (unless it's zero)

they can speed up....

maybe for homework or extra work
