This resource contain links to video resources that demonstrate strategies for teaching mathematics concepts. 

Learn about differences between multiple representations in 8th grade and in Algebra I, including tables, equations, and graphs.

Given algebraic, tabular, and graphical representations of linear functions, the student will determine the slope of the relationship from each of the representations.

Given a pair of similar figures, including dilations, students will be able to generalize that the lengths of corresponding sides are proportional.

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.

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.

Given information in a geometric context, students will be able to use informal arguments to establish facts about the angle sum and exterior angle of triangles, the angles created when parallel lines are cut by a transversal, and the angle-angle criterion for similarity of triangles.

Given a graph of two simultaneous equations, students will be able to interpret the intersection of the graphs as the solution to the two equations.

Given rotations, reflections, translations, and dilations, students will be able to develop algebraic representations for rotations, and generalize and then compare and contrast the properties of congruence transformations and non-congruence transformations.

Given a set of data with no more than 10 data points, students will be able to determine and use the mean absolute deviation to describe the spread of the data.

Given a population with known characteristics, students will be able to use a variety of methods to generate random samples of the same size in order to understand how a random sample is representative of a population.

Given problem situations, the student will determine if the solutions are reasonable.

Given application problems, the student will use appropriate tables, graphs, and algebraic equations to find and justify solutions to problems.
