then the two quantities are said to be in proportion. For instance, let us consider the distance covered by a train in a given interval of time and speed. We can observe that if the speed is more, the train will travel more distance...
Understanding Students continue their investigation of ratios by exploring graphical representations of the sum of two ratios. They should recognize that the sum of two equivalent ratios results in ratio equivalent to the original; and that the coordinates representing the ratio lie on the same line....
Ratios and Proportions / Ratios and Rational Numbers Grade Level 6,7,8 Activity 9 of 15 In this lesson, students compare graphs to make conjectures about slope and compare slopes in terms of the difference in rates of change.Planning and Resources Objectives Students should be able to use ...
Ratios and Proportions / Ratios and Fractions Grade Level 6,7 Activity 6 of 15 This lesson allows students to explore the differences and similarities between ratios and fractions. A ratio may be associated with a value; the value of a ratio a:b is the quotient abab (if b is not 0)....
Ratios and Proportions / Connecting Ratios to Equations Grade Level 6,7,8 Activity 10 of 15 Students generate slope triangles from the graph of a collection of equivalent ratios, thus leading to the notion of a proportional relationship. They use parallel grids to compare the tables, graphs, ...
Ratios and Proportions / Ratios Within and Between Scaled Shapes Grade Level 7,8 Activity 15 of 15 In this lesson, students use ratios to explore relationships that result from scaling figures and use reasoning to determine missing values for a given shape....
