I've only ever sown a large lawn in one go but, logically, it will depend on how many bare patches you have and how big they are but I would suggest starting with trays of 24 one to two inch cells of grass babies. When they have a good root system, plant them out 3 to 4 inches apart and water in well.
Keep them watered and let them establish before you start mowing them. Set the blades high at 2" for their first summer so they have enough leaf to provide energy to send the roots down deep and sustain the plants through their first winter and future droughts. Strong roots also help fight off weeds.
