positioning a plurality of inserts in a concrete form for forming the building block, wherein at least one of the plurality of inserts causes the creation of a tongue and a groove on the building block that allows interlocking two building blocks together back-to-back, wherein the two building blocks are both made with the concrete form, wherein each of the two building blocks comprises:
a front having a top and a bottom;
first and second sides extending from the front, each of the first and second sides comprising a top that is substantially coplanar with the top of the front and a bottom that is substantially coplanar with the bottom of the front, wherein each of the first and second sides comprises the groove that extends downwardly from the top; and
a back coupled to the first and second sides, the back comprising the tongue that extends upwardly from the bottom;
pouring a concrete mix into the form;
allowing the concrete mix to cure; and
