Cut 1 pint of strawberries into quarters and freeze for at least an hour. Once frozen, place three pieces into the bottom of each champagne flute. Fill each glass about two-thirds of the way full with champagne. In a cocktail shaker, combine tequila, strawberry schnapps, limeade, and sugar. Shake vigorously and strain, dividing equally between the flutes. Garnish each with a lime wedge. Serves 10.
