a breadboard has holes all over it designed to fit the leads of electrical components. these holes are connected in columns by conductive metal strips. on each breadboard there are always two sets of two rows on top and bottom. these are connected horizontally. these are usually used for the + and - contacts of the battery.
below i have attached an image showing how this pattern is arranged by outlining connected holes in green. i did not outline everything, just enough to show the pattern.
you use special jumper wires to go from one column/row to the next. a box of multiple sizes of these jumpers can be found at most radioshacks for quite cheaphttp://www.radioshack.com/product/index.jsp?productId=2103801
or of course in ible style you can make your own
