The document outlines a third grade lesson plan about Leonardo da Vinci's role as an inventor for the Italian government. Students will explore da Vinci's invention sketches from his notebooks and make guesses about what each invention was meant to create using an online game. The game allows students to check their guesses while learning how each invention was theoretically designed to work. At the conclusion, students will be prepped for the next class about da Vinci's mirror writing techniques. The teacher will assess student understanding through observation and questions.
