Preparation
Presentation
 Directress introduces the child to the Division Board and selects a division table to work with. For the first question, 24/9, Directress takes 9 skittles and says, "These 9 skittles represent 9 children". And she places the skittles along the top of the board.
 Then Directress asks the child to count 24 green beads, and asks him to divide the 24 beads to 9 children. At the end, the child will find that he could not divide the beads equally. After distributing 2 beads each to a child, the remainder 6 beads could not be divided equally. Hence, we move the remainder 6 beads down to the bottom of the board and explain to the child that 24 divided by 9 is equal 2 remainder 6.
 Remove 1 on the skittle and now we have 8 skittles. Ask the child to divide the 24 beads now. The child will find that each skittle (child) has 3 beads. Hence, 24 divided by 8 is equal 3.
 Encourage the child to work through the Division Table.
