A Game Changer for High School Social Studies
Investigate was created to bring rigor, coherence, and real inquiry back to high school social studies, ensuring students experience learning as active, relevant, and meaningful. By providing leaders with a coherent, standards-aligned foundation and teachers with lessons that amplify their strengths, the program helps students build the critical-thinking, communication, and analytical skills they need to succeed beyond the classroom.
Why Investigate?
Anatomy of a Lesson
Step Into an Investigate Classroom
You’ll see students immediately engaged in a compelling question that sparks discussion and activates prior knowledge. With a clear guiding question shaping their thinking, they open their Student Books and begin exploring with purpose—reading closely, examining visuals, and asking thoughtful questions.
As the lesson unfolds, students annotate primary sources, analyze maps, and collaborate to build evidence-based claims while the teacher facilitates discussion and checks for understanding. Students show what they know through authentic assessments, providing clear reasoning and support from evidence. In an Investigate classroom, inquiry drives instruction, evidence shapes conclusions, and students actively construct their understanding of history.
