Abstract
Wall blocks and methods of constructing walls from the wall blocks which have a side connection system interlocking adjacent blocks whereby a side of the block is provided with a channel or slot that is configured to engage a corresponding projection on the adjacent block. The side connection system may alternatively have a connection receiving cavity formed by channels or slots on the sides of the blocks which are configured to align with a channel or slot from adjacent blocks where a connector may be received to interlock the blocks.
