Find Grampy
Grades: 2-4
Summary: "Grampy's favorite game is hide and seek. He is hiding at a fractional distance between the beginning and the end of the hedge.  The picture tells you the number of parts the hedge is divided into. The number of parts is the denominator of the fraction. Grampy is hiding behind one of those parts. The part he is hiding behind is the numerator of the fraction. You are to guess which part he is hiding behind. You may enter only the numerator of the fractional distance where Grampy is hiding.
