Primary Wood Rulers
These rulers don't complicate things. Get a ruler for your specific child's needs. English measurements are along only one side to simplify. Several options are availablethe most streamlined being the one inch only ruler. The other options combine inch measurements in addition to the specific measurement identified:1/16; 1/8; 1/4; or 1/2. Only the inches are numbered; all other measurements use line marking only. ~ Ruth
