Understanding By Design is a framework and accompanying design process for thinking decisively about unit lesson planning. With UBD, the ultimate goal is to think backward, focusing on the big picture: at the end of a unit what is the essential question your students should be able to answer?
A performance task asks students to demonstrate a skill by performing or producing something: Ex.) Make three-point shot
Other evidence could include many items: Ex.) John's coach has reviewed the game sheets and John made five three-point shots. Statistics are an example of traditional assessments.
