This is a reproducible book of 100 word search puzzles. Each puzzle is based on a theme. Each puzzle has at least 40 words to be found. After all the words have been found, the puzzle has not been completed entirely. As a bonus, the remaining extra letters on the grid can be arranged, in the order they are found on the grid, to make a sentence relevant to the topic. The puzzles can be used alone or with other thematically linked materials.
