The words are on a different page than the wordsearch. You have two options for printing – print on two single pages that are stapled but they can removed the front page to do the wordsearch.
I prefer to print one set of the two copies. I take the two pages and put them side by side on the photocopier to print onto 11x17 paper. Since the pages are in landscape format, this means, on the 11x17 paper, you should have the one page on top ( I prefer to put the wordsearch on the top of the paper, with the word list on the bottom).
I give the students 10 minutes to answer the words in the box on their own. After, we go through to make sure they have the correct words. Then they get time to do the wordsearch.
