-This presentation comes after working with the golden beads and the 1,10,100,1000 cards.
-There's a child in this presentation which makes it more effective for new Montessori teachers to see how the lesson is demonstrated.
-This lesson can be presented in one presentation if the child is advanced as in the video or divide it on two lessons which we recommend. First, let the child practice the layout then in another presentation you can show the child how we compose numbers and expand them.
