GCSE Maths Sequences search worksheet
I hate wordsearches where all the words are given, especially in Maths. What are they learning? What I do like to do is create puzzles, like this one, where a mathematical skill is required to generate the values that need to be found in the puzzle.
One sequence seems to repeat, make sure you find both of them otherwise the code doesn't quite work out right.
This takes almost a full lesson.
