Think-Tac-Toe boards are a great way to provide choice, increase motivation, and have students make products to share. This is a gifted strategy typically used at the end of the unit of study. It matches each of Gardner's Multiple Intelligences to a specific tasks about World War I. This could be an enrichment activity, project grade, or fun activity within the classroom.
This is one of my favorite activities to do all year! There are reading choices, math choices, building choices, and writing choices for students. BrainPop is one of the best resources and there are mentioned activities from BrainPop that students used for the choice board. Please refer to the WWI BrainPop video and resources for more.
