Angle Error

This afternoon I was assisting in a maths lesson where two children independently made the same error:  they both read the above angle as 160°.  They seemed to be interpreting the curved arc as a leading 1 of the number.  The original diagram on the board, although hand-drawn, seemed quite clear to me, but it obviously wasn't to them.
