My son Jacob is starting to work long division in his Math class in 4th grade. It is a source of some painful memories as I remember how much I struggled with it. In retrospect, this is funny because I went on to get a degree in Math.
However, I rediscovered a critical tool in my studies, the Dixon Ticonderoga pencil as pictured above. This was the ultimate math tool that I used through college. It always felt good in my hand, had a amazing eraser, and it always sharpened up so nicely. Simply stated, this is just plain better than any pencil. We bought a box for use at home, and it sure is canceling out the pain of reliving long division.
