But why are you using fractions? What is it about fraction knowledge that is
required for students to obtain a correct solution?
You have four different fractions placed somewhere on the grid. Students don't
really need to know much about fractions, except converting from picture to a/b
form to complete the fractional part of you sudoku.
Could you add another element, and have each quarter of the large puzzle demand
a different representation of the fraction? So, the upper left fourth would be
a diagram; the upper right could be the fraction in reduced form; the lower left
could be an equivalent fraction that has been converted using c/c where c is an
integer not equal to 0 or 1; and the lower right quarter might be converted
using d/d, etc. You could also have some puzzles that use decimal
representation and/or percent representation. Lots of choices!
Just a thought...
