This project is enjoyed a great deal by my students and takes 2-3 class periods. Materials I provide are file folders (legal size is best), dollar store playdoh, and plastic army guys, glue sticks and scissors. (if you have other craft supplies, bring those in for students to make fences or trees)
Once the battle scenes are complete, I place them around the room and then create a crossword puzzle with one question specific to each battle. Students then get to walk around and see each other's work while filling in their puzzles.
At the end of each semester, I ask students what they enjoyed the most about class and this ranks #1 consistently. During the project time, students work independently and I play period music and print off pictures and documents that they send me.
