Heat oven to 400°F. Lightly grease cookie sheet. In large bowl, combine flour, oats, 1/4 cup sugar, baking powder and salt; mix well. Cut in margarine with pastry blender or two knives until mixture resembles coarse crumbs. Stir in currants. In small bowl, combine milk and egg; blend well. Add to dry ingredients all at once; stir with fork just until dry ingredients are moistened. (Do not overmix.) Turn dough out onto lightly floured surface; knead gently 8 to 10 times. Roll or pat dough into 8-inch circle about 1/2 inch thick. Sprinkle with combined remaining 1 tablespoon sugar and cinnamon. Cut into 10 wedges; place on cookie sheet. Bake 12 to 15 minutes or until light golden brown. Serve warm.
