Sophia: Determining Proportionality Using Graphs and Tables

In this frequency worksheet, students interpret histograms, bar graphs and tables.  They examine frequency charts and comparison line graphs.  This three-page worksheet contains 4 problems.  Answers are provided on the...

There may be a right answer, but there isn't one right way to solve the problem. This video goes through a word problem and solves it in three ways: algebraically, numerically, and graphically. Go step by step as the narrator explains...

Are these two given ratios proportional? One quick and easy way to answer this question is to cross multiply the two values. If the products are equal then they are proportional ratios. If they are not equal then they are not...

Use Glencoe's randomly generated self-checking quiz to test your ability to use graphs to make predictions. Each question has a "Hint" link to help. Choose the correct answer for each problem. At the bottom of the page click the "Check...

Students learn to locate the real number solution of a linear equation using tables. They also learn to locate the real number solution of a linear equation using graphical method on a Cartesian (x-y) graph.

Show your class how to use properties to make graphing easier with a resource that explores the graphs of quadratics. Using tables to determine the points to graph, pupils discover the symmetry of parabolas in...

So many methods and so little time! The efficient method of graphing a linear equation depends on what information the problem gives. Pupils learn three different methods of graphing linear equations. They graph equations using...

Become a master at creating visual displays. Using a provided list of heights, users of the interactive create a bar graph and a histogram. They answer a set of challenge questions based on these data representations.

Students learn to estimate the solution set, in real numbers, of a linear inequality using graphical methods on a number line and on a Cartesian (x-y) graph. They also learn how to solve inequalities using tables.

Students learn to locate the real number solution of a system of linear equations (two equations and two variables) with the help of tables and graphs. They also learn to graphically illustrate the types of solutions expected for a...
