Day 12: The Elusive Concept of Continuity
I love foldables!! If you haven’t explored this hands-on, learning strategy, you should. Although most resources for math foldables online revolve around core course topics (Algebra 1, Geometry and some Algebra 2), many subject areas use foldables and interactive notebooks as a means for students to explore new ideas, creatively interact with new ideas and as a way for students to process the information presented in class. In the past, students have struggled with the idea of discontinuous functions and continuity at a point. So I put together a 4-flap foldable for continuous at a point calculus definition (in precalc introduction form) and another 4-flap foldable highlighting discontinuous functions. We looked at an example of the discontinuous function type and discussed which condition of a function being continuous at a point was violated. Then the students glue the foldable in their notes.
