What does Mr. Jansen's approach to math instruction illustrate about teaching methods?

Mr. Jansen's approach to math instruction illustrates the importance of building upon existing knowledge of math. This method recognizes that students come into the classroom with varying levels of understanding and prior experiences. By leveraging what students already know, Mr. Jansen can help them make connections to new concepts, facilitating deeper understanding and retention of material.

This approach fosters a learning environment where students are encouraged to integrate their existing knowledge with new content, enhancing their overall comprehension and problem-solving skills. It aligns with constructivist teaching principles, where learners actively construct their own understanding based on prior knowledge and experiences. By affirmatively using and expanding on what students have already grasped, the instruction becomes more relevant and meaningful, ultimately supporting better educational outcomes.
