# Introduction to the Montessori Decimal Board Part 2

Let's continue to look at the Montessori Decimal board. I am a bit fluid in terms of how I give the lessons and obviously adapt to my students. Some of the previous lessons which you can see here could be merged with these ones if needed.

The Lesson - Introduction 4

Have the Yellow Decimal Board out along with the fraction strip so student can see how 0.1 compares to 1/10.

1) The teacher gives a student a quantity and has the student select the disks and places it on the board

2) Dependent on the student you may wish to write what you have made on a piece of paper so the student can see what the words look like to go with the quantity (see picture above). Continue with other single numbers e.g 6 hundredths, 9 thousandths.

3) Students can now do this activity with a peer.

The Lesson - Introduction 5 Exchanging

1) Select an amount bigger than ten e.g. twelve tenths. Ask the student to make the number - again you may wish to write down what the student has made.

2) Go over with the student what happens when we get 10 or more in a column - we have to exchange.

3) Demonstrate the exchange. Again you may wish to write down what you have made in words.
