This real world problem is appropriate for mental mathematics and students should be encouraged to think through the solution mentally.

In this lesson, students find 100% of a quantity (the whole) when given a quantity that is a percent of the whole by using a variety of methods including finding 1%, equations, mental math using factors of 100, and double number line models. Students solve word problems involving finding 100% of a given quantity with and without using equations.

Students will be given a website to research and answer questions about how real estate and commission work. Students will be given actual real estate listings from across the world and asked to solve for how much commission they would earn by selling real estate in different countries, given the respective commission rates. This lesson was developed by Sarah Sykes as part of their completion of the North Carolina Global Educator Digital Badge program. This lesson plan has been vetted at the local and state level for standards alignment, Global Education focus, and content accuracy.

Students will solve for the percent change in population for a countries across specific decades. Students will then research what happened in the country between specific decades that may have contributed to a drastic change. This lesson was developed by Sarah Sykes as part of their completion of the North Carolina Global Educator Digital Badge program.

Students will be given interest rates for some countries around the world, and they will be asked to solve interest questions involving those respective rates. Students will then use research material to investigate what interest rates do for a community, how interest rates differ around the world, and how interest rates affect communities around the world. This lesson was developed by Sarah Sykes as part of their completion of the North Carolina Global Educator Digital Badge program. This lesson plan has been vetted at the local and state level for standards alignment, Global Education focus, and content accuracy.

Students will build of off the previous lesson by analyze the percent change of minimum wages between 1990 and 2016. After students have calculated the percent change, the students will do some research to determine what sort of events could have caused the drastic change in the minimum wage. This lesson was developed by Sarah Sykes as part of their completion of the North Carolina Global Educator Digital Badge program. This lesson plan has been vetted at the local and state level for standards alignment, Global Education focus, and content accuracy.

Students will estimate the minimum wages in countries around the world. Once being told by the teacher what the minimum wage actually is, the students will calculate their own percent error for each country. This lesson was developed by Sarah Sykes as part of their completion of the North Carolina Global Educator Digital Badge program. This lesson plan has been vetted at the local and state level for standards alignment, Global Education focus, and content accuracy.

This lesson is designed to wrap up the unit with an assessment and individual project. Students will complete an short in-class assessment on Unit Rates and Proportions. Students will begin their individual research necessary to complete a global project based on the previous tasks within this unit. This lesson was developed by Elizabeth Hicks as part of their completion of the North Carolina Global Educator Digital Badge program. This lesson plan has been vetted at the local and state level for standards alignment, Global Education focus, and content accuracy.

Students will develop an understanding of the term "Mark up" and the difference between the markup and retail price of an item. Students will be able to use a proportional relationship in calculating the mark up and discount for an item. The will develop an understanding of how manufacturers and retail stores make a profit on items sold. This lesson was developed by Elizabeth Hicks as part of their completion of the North Carolina Global Educator Digital Badge program. This lesson plan has been vetted at the local and state level for standards alignment, Global Education focus, and content accuracy.

Students will use global information obtained in previous lessons; such as poverty levels, to calculate percent change. Students will develop an understanding "Percent Change" and how to calculate it using proportions. This lesson was developed by Elizabeth Hicks as part of their completion of the North Carolina Global Educator Digital Badge program. This lesson plan has been vetted at the local and state level for standards alignment, Global Education focus, and content accuracy.

Students will learn and understand tax rates and how they are determined. They will investigate the various rates across the country and determine how they are calculated. This lesson was developed by Elizabeth Hicks as part of their completion of the North Carolina Global Educator Digital Badge program. This lesson plan has been vetted at the local and state level for standards alignment, Global Education focus, and content accuracy.

This lesson will pull knowledge previously gained within the students' ELA class while studying types of homelessness locally and nationally. Students will determine a list of necessities to live and determine the unit cost of those necessities. This will allow students to develop an understanding of cost of living. This lesson was developed by Elizabeth Hicks as part of their completion of the North Carolina Global Educator Digital Badge program. This lesson plan has been vetted at the local and state level for standards alignment, Global Education focus, and content accuracy.

The lesson will allow students to work collaboratively to develop and individually to develop an understanding of living in poverty. They will research, investigate, and discuss how the national poverty level is calculated. While examining poverty on the local and national level, they will be given the opportunity to use percentages in their calculations. This lesson was developed by Elizabeth Hicks as part of their completion of the North Carolina Global Educator Digital Badge program. This lesson plan has been vetted at the local and state level for standards alignment, Global Education focus, and content accuracy.

Students will build upon reasoning of ratios and rates to formally define proportional relationships and the constant of proportionality. They explore multiple representations of proportional relationships by looking at tables, graphs, equations, and verbal descriptions, extend their understanding about ratios and proportional relationships to compute unit rates for ratios and rates specified by rational numbers.

For this activity, students solve problems to determine the amount to be paid after a discount has been applied.

This lesson unit is intended to help teachers assess how well students are able to interpret percent increase and decrease, and in particular, to identify and help students who have the following difficulties: translating between percents, decimals, and fractions; representing percent increase and decrease as multiplication; and recognizing the relationship between increases and decreases.

Students will use candy to convert fractions to decimals and to discuss the ways in which this application might be used on a job, and what kind of jobs requires this skill.

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.
