Mix the water, sugar and yeast together in a bowl then let it sit for about five minutes until the yeast is dissolved.
Add 2 cups of the flour and save the last cup for for the next step. Add the salt and olive oil and mix well.
now you can, continue to add the flour and stirring until the mixture becomes dense enough to be worked on a wooden board.
Let the dough rest on the board, covered with a dampened kitchen towel a couple of hours, until double its size.
Its now time to divide the Pita dough into 6-8 portions and shape them into balls.
Cover again the balls with the kitchen towel until they double their size, it usually take about an hour.
