 * Pencil and paper
 * Skittles

Preparation
This is an individual presentation.

Presentation

 * 1) Have the child bring out the two trays.
 * 2) Write two fractions (with the same denominator): 2/6 + 3/6 =
 * 3) Show the child that we first take out 1/6 two times (2/6).
 * 4) Place these in front of the tray.
 * 5) Then take out 1/6 three times (3/6).
 * 6) Have the child count how many 1/6 there are. (5)
 * 7) Show the child how to write the answer as shown: 2/6 + 3/6 = 5/6
 * 8) Read the whole equation with the child.
 * 9) Write another addition problem and have the child do it.
