Presentation 1

Begin the work cycle. This is a group exercise.

One child is put in charge of the bank.

Give each child in the group a felt – lined tray.

The Montessori Directress makes up the dividend, such as 3663 with the large number cards and places it on the bottom right hand corner of the child’s tray.

The child goes to the bank and collects the corresponding amount of beads.

The Montessori Directress then shows the child how to lay out his beads on the top left hand side of the mat and the cards to the right of that.

The Montessori Directress then tells the three children with trays that we are going to share the beads evenly amongst them and that each child will receive the same amount of beads.

The Montessori Directress starts sharing or dividing the number starting with the thousands this time.

The Montessori Directress gives each child a 1000 cube, then two 100 bead squares, then two 10 bead bars, and finally one unit bead each.

The Montessori Directress asks each child to collect and place the corresponding small number cards below the beads on their trays.

The children discover that each of them have the same numbers.

The Montessori Directress explains that the answer is what we see on each child’s tray and each child received 1221 but that we only need to write it once, so 1221 is the answer.

The Montessori Directress takes one set of small number cards from one of the three children and places them on the operations mat below the large number cards.

The Montessori Directress restates the sum, emphasising the point that we started with a large amount and we shared the beads evenly amongst the children and we call this “dividing”.
