A great hook for your class to discuss ratios! TV screens and many mobile devices have a widescreen aspect ratio due to the ratio that the majority of video content has been recorded. Future technologies promise flexible displays nearly the thickness of a piece of common paper. However, is the aspect ratio of a piece of paper compatible with the common 16:9 aspect ratio we use today? Explore this real-world scenario with the "Question of the Day" included in this document.
Works well as a warm up to introduce equivalent ratios. Otherwise, can be used as an interactive class/group activity to discuss different ways of proving a statement. These sheets will help your students organize their work/thinking and share with their peers.
