Repeat each measure up to 4 times before going to the next one. Once comfortable with that, play each measure 3 times, then two, then one, etc. After you are comfortable in this key, transpose to another and try to see the next chord quality before you play it. You can also take this exercise a bit further by adding more chord qualities, but I think this is a good starting point. Don't worry about playing in one breath, but you can make that a focus if you'd like, but by doing that, speed becomes a factor.
