Exploring Ratios and Proportions: 6.RP.3
Solving proportions: 6.rp.3, warm up: “what do you notice..., what do you wonder”.
Using fraction strips, have students discuss patterns and relationships, and then predict the next table shading...
There are 4 different sized rectangles. All rectangles are different sizes. The first rectangle is cut into 2 equal parts (one row of 4), one of which is yellow. The second rectangle is cut into 4 equal parts, 2 of which are green. The third rectangle is cut into 6 equal parts, 3 of which are blue. The last rectangle is cut into 16 equal parts (2 rows of 8) without any shading.
Having student explore and discuss patterns and relationships they see, as well as predict the shading of the next rectangle will help them demonstrate any prior knowledge. Depending on internet access, this can either be printed, projected, or on a smartboard.

Khan Academy Video: Intro to Ratios
This Khan Academy video could be either an introduction or review for equivalent ratios, depending on the student’s background knowledge.
Solving Proportions
Khan Academy: Solving Proportions
This Khan Academy lesson walks through how to set up and solve a proportion. Both of these videos are connected to practice problems, for students at varying levels to get
Application/formative assessment:
Nana Paint Mix-up
This is where the student can practice setting up a proportion in a “real life” situation. These are like authentic story problems that students have to determine the important data, find relationships, determine what needs to be solved, and solve it. Having students justify their reasoning, as well as explain their problem solving process will be a great formative assessment of how much the students understand.
Practice and summative assessment
Algebra by Example
3.4 Writing Proportions
3.5 Solving Proportions
Under: Linear Equations in Algebra by Example , look at sections 3.4, 3.5
Although they may need additional practice to fully develop fluency, these sheets help the students demonstrate their understanding. Students start by examining other “student work”. If there is an error, they have to determine the mathematical errors they made. If there is not an error, they explain the reasoning in the steps, to show deeper understanding. Their level of understanding will be evident in their explanation of the other students work. The student is also asked complete similar problems, to show their understanding. Answer keys are available.

- 6.1: Ratio and Proportion Examples and applications of ratios are limitless: speed is a ratio that compares changes in distance with respect to time, acceleration is a ratio that compares changes in speed with respect to time, and percentages compare the part with the whole. We’ve already studied one classic ratio, the ratio of the circumference of a circle to its diameter, which gives us the definition of π.
- 6.2: Introduction to Ratios and Rates We use ratios to compare two numeric quantities or quantities with the same units.
- 6.3: Introduction to Proportion In this section, we equate ratio and rates in a construct called a proportion.
- 6.4: Unit Conversion - American System In this section we will develop a technique for converting units used in the American system. We begin with a discussion of common measurements of length in the United States.
- 6.5: Unit Conversion- Metric System The metric system of units is the standard system of units preferred by scientists. It is based on the base ten number system and its decimal format is more friendly to users of this system. There is a common set of prefixes adopted by the metric system to indicate a power of ten to apply to the base unit.
- 6.6: American Units to Metric Units and Vice-Versa We often need to convert from the American system of units to the metric system of units or vice-versa (imagine traveling to a European country using the metric system). That will be our focus in this section.

"In Module 1, students build on their Grade 6 experiences with ratios, unit rates, and fraction division to analyze proportional relationships. They decide whether two quantities are in a proportional relationship, identify constants of proportionality, and represent the relationship by equations. These skills are then applied to real-world problems including scale drawings." Eureka Math ...
The Golden Ratio has been known since the time of Euclid. Ancient and modern architects have long held that the most pleasing rectangular shape is the one whose ratio of length to width is equal to the Golden Ratio. The comparison of two ratios, such as AB / AC = AC / CB, is called a proportion. Proportions are used in a number of practical ways.
The comparison of two ratios, such as AB/AC = AC/CB, is called a proportion. Proportions are used in a number of practical ways. For example, if 5 cans of tomato sauce cost 2 dollars, we can find the number of cans that can be purchased with 10 dollars by comparing two ratios in a proportion:
2 Lesson 1: Equal Ratios and Proportions Vocabulary: 1. Ratio: A comparison of two quantities by division. Can be written as b a, a: b, or a to b. (b = 0) 2. Proportion: An equation that shows that two ratios are equivalent (equal). 3. Cross Product: In two ratios, the cross products are found by multiplying the denominator of one ratio

They are able to do some hands on exploring with sorting ratio cards by digging into relationships. Students can then work on a three act math problem, and dig into the entire process of writing and solving a proportion problem. They end by evaluating "student work" on the topic, explaining the steps and what went wrong in the problems.
