iBlocks are innovative, experiential PBL activities that engage students in critical thinking, teamwork, and fun! An iBlock is a student-led, teacher-guided activity that focuses on exciting topics and design thinking, which builds cross-curricular skills and culminates in a capstone project. Each iBlock is purposefully designed to provide clear project guidelines but flexible enough to adapt to the needs of all students. Built around the engineering design process, iBlocks encourage trial and error as students interact authentically with real-world problems and questions.
