  • He also takes away 2 ten bed bars, and 2 hundred bead squares from the mat and places them on his tray.
  • Show the child how to place the small number cards under the large number cards to remind him of the number that he subtracted.
  • The tray with the beads is then set to one side on the mat.
  • The Montessori Directress then tells the children that we must count the beads left over on the mat to find our answer.
  • We start counting the units, then the tens, then the hundreds.
  • The child collects and places the corresponding small number cards below the beads at every stage.
  • The Montessori Directress re-states the sum. She also says that we did “subtraction” – that is, we started with a big amount and now we only have a small amount of beads left.
  • End the work cycle.
