A plurality of field blocks is arranged in a second course atop the first course wherein each field block includes a lower surface that interfits with the upper surface of at least one of the leveling blocks and a wall defining a field block void aligned with the leveling block void of the one leveling block. A cementitious material is disposed in an aligned field block void and leveling block void of at least one of the field blocks and at least one of the leveling blocks, respectively. ## Claims ### Claim 1 A wall construction block combination, comprising a block comprising a front surface, a back surface, a top surface, a bottom surface, and a plurality of webs extending between the front surface and the back surface to define at least two voids, each with a void perimeter, wherein at least one of the voids is at least partially bounded by a ledge within the void and along the void perimeter of at least one of the two voids; and structures on the top and bottom surfaces defining at least one protrusion at one of the top surface and the bottom surface and a recess at the other of the top surface and the bottom surface wherein the protrusion and recess are dimensioned to have an interfitting relationship with corresponding protrusions and recesses of substantially identical blocks; and an insert separate from the block and disposed on the ledge, the insert having a surface area dimensioned to have a portion of its perimeter supported by the ledge. ### Claim 2 (depends on 1) The wall construction block combination of claim 1, wherein the block further includes first and second end surfaces each including structures defining at least one end protrusion at the first end surface and an end recess at the second end surface wherein the end protrusion of the block is adapted to interfit with an end recess of a still further identical block. ### Claim 3 (depends on 1) The wall construction block combination of claim 1, wherein the top surface includes two spaced protrusions. ### Claim 4 (depends on 3) The wall construction block combination of claim 3, wherein the bottom surface includes two spaced elongate shoulders defining the recess. ### Claim 5 (depends on 1) The wall construction block combination of claim 1, wherein the insert includes an opening adapted to support rebar. ### Claim 6 (depends on 1) The wall construction block combination of claim 1, wherein at least one web includes a frangible portion that may be removed to create a recess adapted to receive a section of rebar. ### Claim 7 (depends on 1) The wall construction block combination of claim 1, wherein the block further comprises a further void, wherein the at least two voids are of a first size and wherein the further void is of a second size. ### Claim 8 (depends on 7) The wall construction block combination of claim 7, wherein each further void comprises a central void and at least one end void disposed at an end of the wall construction block is of a size about one-half the second size. ### Claim 9 (depends on 8) The wall construction block combination of claim 8, further including cementitious material disposed in the end void. ### Claim 10 (depends on 1) The wall construction block combination of claim 1, wherein the block comprises a corner block. ### Claim 11 (depends on 1) The wall construction block combination of claim 1, further comprising a plug of cementitious material formed atop the insert. ### Claim 12 (depends on 11) The wall construction block combination of claim 11, wherein the plug extends upwardly into a void of an adjacent wall construction block adapted to be positioned atop the wall construction block. ### Claim 13 (depends on 2) The wall construction block combination of claim 2, wherein a channel that extends in a height direction is disposed between the at least one end protrusion of the first end surface of the block and the at least one end outer protrusion of the second end surface of the still further identical block.
