Preheat oven to 425*.

In a large bowl, combine flour, baking powder, salt, and sugar. Cut in the shortening with a dough cutter until mixture resembles coarse meal.

Gradually stir in milk until dough is formed.

Turn onto a floured surface and lightly knead about 10 times.

Using a rolling pin and your hands to form the dough into a rectangle, use a knife to cut into 6 pieces.

Place on a baking sheet and bake for about 13-15 minutes.
