No more toothpicks and glue! The K'NEX® Education Intro to Structures: Bridges set is designed to introduce students to the history, function, structural design, geometry and strength of bridges while providing opportunities for them to acquire skills using a hands-on, inquiry-based approach to information and concepts. The Teacher's Guide provides the information and resources required to build your students' understanding of scientific, technical and design concepts and to channel their inquiries into active and meaningful learning experiences. Set includes 207 K'NEX® parts – enough to build 13 fully-functioning replicas of real-world structures! Supports 2 – 3 students in grades 3 -5. Building instructions and teacher's guide aligned to national education standards and Common Core Mathematics included. Packaged in a strong storage tray with snap-on lid. STEM Education focuses on science, technology, engineering and mathematics concepts taught through problem-solving, discovery, exploratory learning and critical thinking. STEM Education requires students to be active participants in the learning. K'NEX® models offer hands-on learning opportunities that encourage scientific inquiry, investigation and experimentation. Our inquiry-based lessons challenge students as they build, investigate, problem solve, discuss, and evaluate scientific and design principles in action. Aligned to Science, Technology, Engineering, and Math standards.
