As a middle school math teacher, you want your students to understand the concept of proportional relationships and linear equations. This lesson...
Proportional relationships in mathematics are often represented in equations and graphs. A proportional relationship is one in which the ratio of two variables is constant. This means that for any increase or decrease in one variable, there will be a corresponding increase or decrease in the ...
6,7,8 Ratios & Proportions 11. Proportional Relationships This lesson focuses on the relationship between the unit rate - or slope - of a line and the equation. Building Concepts in Mathematics The Program About Building Concepts Watch the video about Building Concepts Watch the video about...
Findings are presented from an analysis of how six future middle-grade teachers reasoned with strip diagrams and a variable parts perspective on proportional relationships to develop and explain equations in two variables. One equation was for two quantities varying together and one was for a line ...
Size is proportional to the weight of the study in a random effects meta-analysis. Arrows indicate that the true values are beyond the range of the axis. The dashed line indicates the overall C statistic. Representative references and expanded acronyms for each cohort name are provided in e...
(2) A radius vector joining any planet to the Sun sweeps out equal areas in equal lengths of time. (3) The squares of the sidereal periods of revolution of the planets are directly proportional to the cubes of their mean distances from the Sun. These laws would eventually lend help to...

relationships between multiple representations. With regard to vector algebra, decades of research on school and university mathematics and physics education have revealed that students encounter difficulties with basic vector concepts, such as interpreting graphical properties like vector decomposition (e.g....
The relationships between ODEs and dynamic processes are so basic that we explore the connections right from the start. Throughout the chapter, simple processes are introduced and modeled with ODEs. We hope users of this text will use numerical solvers to approximate and graph solutions of ODEs;...
