Students choose a path from the start to finish, moving from one adjacent square to another (horizontal, vertical or diagonal) solving the equations as they go. If they take the most direct route, the equations are more difficult. The answers are often fractional to promote students writing fractional answers rather than incorrectly rounded decimal answers (a common cause of dropped marks in exams).
I think the errors pointed out are still on the pdf version of this resource. I downloaded it today and there are still there.

Thanks for pointing out the errors. They have now been amended.

Great resource and go for independent learning/choices.
I have also discovered two more mistakes with the solutions however. Third column from the left and four down. (3x+1)/2 = (x-5)/7 Solution should be x = -17/19.
And the one to the right of this one. 3(2x+1)/2 = (x-5)/7 Solution should be x = -31/40

Actually, the equation 10c=3c can be solved as the solution is c=0. A problem occurs because as the solution is c=0 we are dividing by zero in the original equation, which isn't possible. I've adapted the question to read 3c/2=5c which reduces to 10c=3c and so has the same solution (c=0), but there is no worry of division by zero occurring.

I have discovered a problem with this resource. on the second row, middle column, it is an impossible question. once you go through the cross multiplication, you get 10c = 3c which simply isn't possible

This is an excellent resource. I like the fact that students can choose their route to suit their ability/confidence in solving equations.
