What children learn in Level 12

  • An area model takes room to draw. We can list the same parts in a stack instead. Each line is one part of the model.
  • Start with the ones: 6 times 3, 6 times 40, and 6 times 200. Then do the tens: 30 times 3, 30 times 40, and 30 times 200.
  • Add all the lines, and you get the same answer as the area model.
  • The notes beside each line keep your thinking clear. Each one tells which parts you multiplied.

Georgia's K-12 Mathematics Standards:
