Fundamentals: 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. 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.
Calculating Slope
Learning Goal: To calculate the slope of a line on a graph.
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.
