  8. When the child is comfortable doing this, have him bring quantities from two different place values. For instance: "Please bring me 2 tens and 5 units." This may take a few presentations before the child gets to this point depending on the age and abilities of the child.
  9. Place a quantity of beads on the tray and ask the child to name the quantity. (This step acts as the third period in the Three Period Lesson.)
