Relationships and Graphs

A Concept-Builder is an interactive questioning module that presents learners with carefully crafted questions that target various aspects of a concept. Each Concept Builder focuses the learner's attention upon a discrete learning outcome. Questions target that outcome from a variety of angles using multiple difficulty levels or varying activities. Learners ponder the given information and answer questions in the hopes of earning Stars and Medals. These Stars (for answering questions) and Medals (for completing levels or activities) are displayed on the screen, allowing a teacher to track student progress. The following Concept Builders target concepts in an introductory unit about Relationships and Graphs.

Experiments and Variables      
Learning Goal: To understand how an experiment’s purpose provides guidance to the design of an experiment and the manner in which data are collected and displayed.

Proportional Reasoning      
Learning Goal: To use proportional reasoning to predict how a change in one variable affects another variable.

Using Graphs      
Learning Goal: To analyze a graph in order to determine its slope (along with appropriate units), to use words to describe the relationship between plotted quantities, and to extrapolate in order to predict an unknown quantity.

Which One Doesn't Belong      
Learning Goal: To use an understanding of the various types of relationships in order to identify which representation is not consistent with the other representations.
