1) The document defines opportunity costs as giving up one thing for another. It provides resources for students to investigate opportunity costs through two texts - a fiction story about a girl choosing between hair accessories, and an informational graphic about a girl choosing activities. 2) Students are asked to identify the opportunity costs in each text and explain what was given up. They are then asked to design a comic showing a personal example of an opportunity cost choice. 3) The document lists common core standards for reading closely, analyzing texts, integrating information, and using technology to publish writing. It aims to build vocabulary and understanding of opportunity costs.
