What says math geek more so than this sweater? Hey it's cute for sure, but don't let your kid wear this till he's all grown up in college. Not that there's anything wrong with it, we actually kind of like it.
The Seven/Eight Year Math Sweater is hand-knit of machine-washable wool and designed to fit the average 1st or 2nd grader. Etsy shop proprietor Amarinalevin HandKnits explains:
The main body of the sweater is a pattern of adding numbers in block shapes. There are also little x's in black. Circling the bottom in green on a dark blue background are Fibonacci numbers. Also circling the bottom and wrists in dark blue on periwinkle is the symbol pi. The back and front are identical. The sleeves have descending and ascending blocks with the prime numbers. Circling the wrists in green on a dark blue background are the various mathematical functions of add, subtract, multiply, and divide. The neck, wrist, and bottom trim is varying shades of green with blue stripes.
