The moon doesn't really change shape, it is always a full, whole, spherical moon. We just can't always see all of it, we can only see the light side. The sun shines on a specific side of the moon, and because earth (and the moon) are always moving, the sun is shining on different areas of the moon every day. During a new moon, the sun is shining on the part of the moon we can't see.
