Resources

Resource ID: M8M2L1* Grade Range: 8 By: ESC13 Content Subject: Math
Given a pair of similar figures, including dilations, students will be able to generalize that the lengths of corresponding sides are proportional.
Resource ID: M8M2L2* Grade Range: 8 By: ESC13 Content Subject: Math
Given a coordinate plane, the student will graph dilations, reflections, and translations, and use those graphs to solve problems.
Resource ID: M8M2L3* Grade Range: 8 By: ESC13 Content Subject: Math
Given a coordinate plane or coordinate representations of a dilation, the student will graph dilations and use those graphs to solve problems.
Resource ID: M8M2L4* Grade Range: 8 By: ESC13 Content Subject: Math
Given multiple representations of linear functions, the student will develop the concept of slope as a rate of change.
Resource ID: M8M2L5* Grade Range: 8 By: ESC13 Content Subject: Math
Given a proportional relationship, students will be able to graph a set of data from the relationship and interpret the unit rate as the slope of the line.
Resource ID: M8M2L6* Grade Range: 6-8 By: ESC13 Content Subject: Math
Given algebraic, tabular, and graphical representations of linear functions, the student will determine the slope of the relationship from each of the representations.
Resource ID: M8M2L8* Grade Range: 8 By: ESC13 Content Subject: Math
Given problems that include data, the student will generate different representations, such as a table, graph, equation, or verbal description.
Resource ID: A1M2L7* Grade Range: 9-12 By: IPSI Developer Subject: Math
Given data in the form of an equation, the student will use the equation to interpret solutions to problems.
Resource ID: M8M2L13* Grade Range: 8 By: ESC13 Content Subject: Math
Given a set of data, the student will be able to generate a scatterplot, determine whether the data are linear or non-linear, describe an association between the two variables, and use a trend line to make predictions for data with a linear association.
Resource ID: M8M2L14* Grade Range: 8 By: ESC13 Content Subject: Math
Given problem solving situations, the student will solve the problems by comparing and contrasting proportional and non-proportional linear relationships.
Resource ID: M8M2L15* Grade Range: 8 By: ESC13 Content Subject: Math
The student is expected to gather and record data & use data sets to determine functional relationships between quantities.
