Of all the materials I've created to help students review for exams, one of the most popular has been the crossword puzzle. If you want something that will be fun and relatively fast for students to use but challenging enough to make them think, crosswords are a great tool! I'm planning to make a complete set for all of my units in AP Psychology this year and I will post them in my store as I get them done. This crossword is the first of four that I have made for the History of Psychology unit. I'll be posting the other three in my store shortly and will follow them with 6 puzzles to help students review Research Methods.
