This lesson will allow students to become familiar with the concept of unit rate. Through an open investigation students will develop methods to find unit rate with a table, equivalent ratios, or an equation. This is a lesson to be used as part of a unit with "Painter Problems" and "How Big Should It Be?"

In this lesson, students view a picture or video of the Statue of Liberty and are asked how long the arm would be if the nose measures 4 feet 6 inches. They measure the length of their own nose and the length of their arm and form a ratio. Using proportions, students compute the length of the statue's arm. In addition to the lesson plan, the site includes ideas for teacher discussion, extensions of the lesson, and additional resources.

In this ratios and proportions video lesson, students will practice reading and understanding the language of word problems; they will use specific words as clues to the mathematical operations embedded in the proportions and ratios problems and use them in context. This resource supports English language development for English language learners.

In this math video lesson, students will analyze and write data for "beans counting" rate of three classmates, then, they will formalize ways to represent rates and develop arguments for comparing and making more elaborated conclusions about them.This resource supports English language development for English language learners.

In this Math video lesson on rates, students will explore ways of writing rates, then, they will develop arguments for comparing and making conclusions about them; finally, they formalize their ideas by making justifications recording the data in complete sentences. This resource supports English language development for English language learners.

In this lesson, students learn about sound. Girls and boys are introduced to the concept of frequency and how it applies to musical sounds.

The purpose of this task is to generate a classroom discussion about ratios and unit rates in context.

CK-12 Foundation's Middle School Math Grade 6 Flexbook covers the fundamentals of fractions, decimals, and geometry. Also explored are units of measurement, graphing concepts, and strategies for utilizing the book's content in practical situations.

For this interactive, students solve problems to find unit rates. Students enter an answer and can click the Check Answer button to see if their answer is correct.

The purpose of this task is to help students see that when you have a context that can be modeled with a ratio and associated unit rate, there is almost always another ratio with its associated unit rate (the only exception is when one of the quantities is zero), and to encourage students to flexibly choose either unit rate depending on the question at hand.

In this video, Ratey the Math Cat, points out the rates and proportions in daily life.

Sample Learning Goals
Understand the concept of a ratio and use ratio language to describe a ratio relationship between two hand heights.
Understand the concept of a unit rate a/b associated with a ratio a:b, and use rate language in the context of a ratio relationship.
Recognize and represent proportional relationships between hand heights.

This is an activity that I like to title, "Making a worksheet More than a worksheet".  Teachers should cut the fourteen questions out, place them in a ziploc bag.  Each group will get a bag of questions and place their answers on the answer sheet.  

This 90-minute lesson (15-minute pre-lesson, 60-minute lesson and 15-minute follow up lesson or homework) asks students to analyze proportional relationships to solve real world and mathematical problems. The examples use recipes, paint, and buildings. Students begin by working individually, then in pairs or threes, and then as a whole class. Student will need calculators, large sheets of paper to make a poster and the lesson materials.

In this activity, students will explore multiplication and division of fractions using several representations to develop fluency. Students will also solve problems involving similarity using proportions.

Students are introduced to an important engineering element the gear. Different types of gears are used in many engineering devices, including wind-up toys, bicycles, cars and non-digital clocks. Students learn about various types of gears and how they work in machines. They handle and combine LEGO spur gears as an exercise in gear ratios. They see how gears and different gear train arrangements are used to change the speed, torque and direction of a power source. This prepares them to apply this knowledge in four associated activities in order to create successful solutions to design challenges that use LEGO MINDSTORMS(TM) NXT robots. A PowerPoint® presentation, pre/post quizzes and a worksheet are provided.
