Students discover that proportions are made up of equal ratios each containing the same building blocks. They, using the Internet, apply their knowledge of direct relationships and proportions to problems in planetary science.
Young scholars solve problems with ratios. In this algebra lesson, students rewrite word problems using algebraic equations and solve using ratio and proportion. They show their understanding of the problems as they relate to the real world.
Students investigate ratios and percents and convert between the two. In this algebra lesson, students write ratios using fractions. They write percents as fractions and decimals and they apply the concepts of the Fibonacci rectangle to solve problems.
Young scholars investigate the use of ratios in scale drawings. In this middle school, cross curricula, mathematics lesson, students scale objects up or down using ratios and find the actual size of something using ratios. Young scholars apply knowledge of ratios to making their own telescope in Science class.
Students determine ratios of a given event. In this ratio lesson, students perform activities to collect statistical information. They perform an experiment by shaking a cup containing beans, comparing the number of marked beans to the total. Students write the ratio as a fraction and as a decimal.
Ninth graders create clinometers using a protractor, weight, and string. They work in pairs to practice sighting objects above or below their line of sight. Students use ratios of right triangles to determine the height of a predetermined object.
Students review equivalent fractions and the rules for equivalent fractions. They are introduced to equivalent ratios. Students write examples of ratios from the board and they come to the board and write the correct equivalent ratios and give reasons for their choices.
Learners study ratios and proportions in word problems. In this ratio and proportion strategies instructional activity, students read and solve a number of word problems. Learners copy and discuss what they believe their strategies are in solving each problem. Students also write their findings and share with the rest of the class.
Seventh graders investigate a ratio found in nature and in numerous pieces of artwork throughout history. The lesson is cross-curricular and builds a sense of appreciation of design for students.
