This is a great set of activity sheets that are wonderful for review or just to fill time as the year comes to an end. I use these in a relay with teams competing for simple prizes (pencils, stickers, etc.). Students group into teams and must complete one activity sheet at a time accurately to move onto the next. I also use map puzzles as another step of the game. Includes content vocabulary and other concepts from World History or World Studies used with word scrambles, crosswords, and other puzzle clue activities. My kids love the activity. Takes 1 standard class period to complete.
