Word wise challenge is a word search game online. The game is copyrighted by National Geographic. Word Wise, as a challenge, is a very simple game. There is not that much words to search for. In fact, there is only about ten words. For an fourth through seven grader, the gam may not be fun — or challenging enough — for them. Possibly a third grader my not even like it. The game would be too easy. For kinder through first, however, it might be fun. If you want to play here is the link.
