Ratio and Proportion
6th - 8th
Middle schoolers review the definition and rules for equivalent fractions. Additionally, they are introduced to equivalent ratios. They write examples of ratios from the board, and they come to the board to write the correct equivalent ratios, giving reasons for their choices.
Concept: Ratios and Proportions
Upper elementary and middle school pupils fill out a chart creating six equivalent fractions and then compare them to six different objects and/or shapes. They group together 16 various terms related to ratios and proportions. Pupils fill in 14 blanks to answer 14 facts about ratios and proportions online.
Ratio and Proportion 7.1
In this calculating ratio and proportion learning exercise, learners write rations in their simplest form, write in the form 1:n for ratios, and solve word problems. Students solve 4 problems.
Ratio and Proportion: Write and Interpret
In this ratio and proportion learning exercise, students explore example problems. Afterwards, they read story problems and use ratios and proportions to find the solution. This three-page learning exercise contains six multi-step problems,
Ratios and Proportions
In this ratios and proportions worksheet, students complete a series of short answer questions based on different charts and word problems dealing with ratios and proportions. Students complete 9 problems.
Balancing the Scales: Understanding Ratios
Students are introduced to the concept of ratios. In groups, they convert sets of numbers into a ratio. After practicing, they use the ratios and proportions to solve story problems. They also calculate map distances and discover map scales.
Proportionality: Modeling the Future
Students explore and examine how patterns, measurement, ratios and proportions are utilized in the research development and production of airplanes. They meet a pilot from the Federal Aviation Association who describes the growth of air transportation and its relationship to mathematical patterns.
The Golden Ratio
Students solve problems using ratios and proportions. For this algebra lesson, students verify proportions, solve for the unknown and use real life scenario to model proportion.
Partying with Proportions and Percents
Examine ratios and proportions in several real-world scenarios. Children will calculate unit rates, work with proportions and percentages as they plan a party, purchase produce, and take a tally. This lesson plan recommends five 45-minute sessions to complete all of the activities, but you can pick and choose what would be most applicable to your curriculum.
Ratio And Proportion
Both intuitive and logistical steps bring Sal and the viewers to the correct answers in these problems using ratio and proportion. An equation with ratios introduces the video, and the skills from that problem lend well to the word problems that follow.
Recipes and Ratios
Students use ratio and proportions to adjust recipe size. In this middle school mathematics lesson, students investigate Native American food and adjust the recipe size for said foods to the number of servings needed to feed the students in the class.
