Elements of MathHooks
The videos added to some hooks are not an essential element of the hook. Instead, the videos are real-world applications that are connected (sometimes loosely) to the concepts at play in the standard. The videos are not teaching tools such as those found on sites like Khan Academy or LearnZillion. Instead, they are there to act as another tool for engagement. Students see how the mathematics they are learning can be used in the real world, from encoding messages using translations to the musicality and mystery of the number pi. In short, the videos are for fun. Enjoy.
