Print out the 20 posters and 'stick' them on the classroom walls. Give each student a starting point. Answer the question on the poster and look for the answer at the top of another poster to work out the order of the treaure hunt. Can be used as a race or a timed challenge to add a sense or urgency!
The students work through the 20 questions, shading in their answers in the grid. When they have finished the 5 'unshaded' numbers in the grid should be recorded in the blank boxes. For the majority of the settlers the 'Target' is found by finding the total of the 5 boxes or for algebraic settlers the target can be the missing expression or solution in a pattern.
