Clear Grid Scale Ruler, 18 inch – Standard + Metric + Grid
This 18″ long, 3mm thick by 2 inch wide ruler makes a useful straight edge and is another invaluable geometry tool.
This gridding scale ruler has so many useful features. There are small, clear cut-outs at every 1/2″ position. The rigid, clear scale also has grid marks of 8×8 per square inch with a 16 count set of lines above the 8×8 grid – extremely useful for children learning parts of a measure and for crafters of all ages! It includes both standard (inches) and metric (cm + mm) measurements and can be used as a centering ruler too. The transparent nature assists in constructions and is made by Alvin Drafting in Germany.
(Bonus: also useful for quilting, sewing and crafts!)
ARE YOU A WALDORFISH STUDENT?
The Waldorfish Geometry instructor recommends a high-quality, sturdy, clear, grid-scale straight edge for her course. We love that this one can also double as a measurement tool in standard or metric, so it’s useful for other math and measurement needs, too.
