Unit Overview



|Unit Overview |

|Content Area: Math |

|Unit Title: Percent Unit: 6 |

|Target Course/Grade Level: Seventh Grade Timeline: 3 weeks |

|Unit Summary: This unit focuses on problem solving with percents. Students learn to apply percent proportions, percent equations, and percent |

|estimation skills to real-world problems. Using decimal and fraction equivalents for percents, students solve problems involving percent of |

|change, sales tax, tip, discount, and simple interest. Students will use the reasoning skills they learn to make decisions in the real world |

|about products and services they intend to purchase. |

|Primary interdisciplinary connections: Language Arts and Technology |

|9.1 21st-Centuries Life & Career Skills |

|Standard 9.1 All students will demonstrate the creative, critical thinking, collaboration, and problem-solving skills needed to function |

|successfully as both global citizens and workers in diverse ethnic and organizational cultures. |

|Strand: A. Critical Thinking and Problem Solving |

|B. Creativity and Innovation |

|C. Collaboration, Teamwork and Leadership |

|Content Statement: |

|9.1.8: A The ability to recognize a problem and apply critical thinking skills and problem |

|solving skills to solve the problem is a lifelong skill that develops over time. |

|9.1.8: B Gathering and Evaluating knowledge and information from a variety of sources, |

|including global perspective, fosters creativity and innovative thinking. |

|9.1.8: C Collaboration and team work enable individuals or groups to achieve common goals |

|with greater efficiency. |

|Leadership abilities develop over time through participation in group and or teams that |

|that are engaged in challenging or competitive activities. |

|21st Century themes and skills: Critical Thinking and Problem Solving, Collaboration, Teamwork and |

|Leadership, Creativity and Innovation |

|Mathematical Practices: |

|7.MP.1 Make sense of problems and persevere in solving them. |

|7.MP.2 Reason abstractly and quantitatively. |

|7.MP.3 Construct viable arguments and critique the reasoning of others. |

|7.MP.4 Model with mathematics. |

|7.MP.5 Use appropriate tools strategically. |

|7.MP.6 Attend to precision. |

|7.MP.7 Look for and make use of structure. |

|7.MP.8 Look for and express regularity in repeated reasoning. |

|Learning Targets |

|Domain: Ratios and Proportional Relationships |

|Cluster: Analyze proportional relationships and use them to solve real-world and mathematical problems |

|Standard # | Standards |

|7.RP.2c |Represent proportional relationships by equations. For example, if total cost t is proportional to the number n of items |

| |purchased at a constant price p, the relationship between the total cost and the number of items can be expressed as t = |

| |pn. |

|7.RP.3 |Use proportional relationships to solve multistep ratio and percent problems. Examples : simple interest, tax, markups and|

| |markdowns, gratuities and commissions, fees, percent increase and decrease, percent error. |

|7.EE.3 |Solve real-world and mathematical problems involving the four operations with rational numbers. (Computations with |

| |rational numbers extend the rules for manipulating fractions to complex fractions.) |

|9.1.8.A.1 |Develop strategies to reinforce positive attitudes and productive behaviors that impact critical thinking and |

| |problem-solving skills. |

|9.1.8.A.2 |Implement problem-solving strategies to solve a problem in school or the community. |

|9.1.8.B.2 |Assess data gathered to solve problems for which there are varying perspective (e.g., cross cultural, gender specific, |

| |generational, etc.) and determine how the data can best be used to design the multiple solutions. |

|9.1.8.C.1 |Determine an individual’s responsibility for personal actions and contributions to group activities. |

|9.1.8.C.2 |Demonstrate the use of compromise, consensus and community building strategies for carrying out different task, |

| |assignments and projects. |

|9.1.8.C.3 |Model leadership skills during classroom and extracurricular activities. |

|Unit Essential Questions |Unit Enduring Understandings |

|What are percents and how are they used in everyday life? |A percent is a ratio that compares a number to 100. |

|How can equivalent fractions be helpful in estimating percents? |In a percent proportion, one ratio represents a part to a whole |

|How can percent equations be applied to real-world problems? |comparison and the equivalent ratio part 100, represents the percent. |

|How is calculating sales tax similar to calculating tips? |A percent of change is a ratio that compares the change in quantity to |

|How are percents related to proportional relationships? |the original amount. |

|Unit Learning Targets |

|Students will ... |

|Find the percent of a number. |

|Estimate the percents by using fractions and decimals. |

|Solve problems using the percent proportion and the percent equation. |

|Find the percent of increase or decrease. |

|Solve problems involving sales tax, tips, discount and simple interest. |

|Evidence of Learning |

|Summative Assessment |

|Find the percent of a number. |

|Solve problems using the percent proportion and percent equation. |

|Solve percent problems finding percent of change, sales tax, tips, amount and percent of discount, and simple interest. |

|Opportunities for Differentiation: |

|Decelerate: Students create samples of the three types of percent problems. Exchange and solve them . |

|Using restaurant menus, students order a meal and calculate the bill, including the tax and tip. Have the students calculate the bill with |

|different percentages for sales tax and tip. |

| |

|Accelerated: Students will estimate the percent of a circle that is shaded. Then work to develop a method to check the accuracy of their |

|estimate; ie – using a protractor and the total degrees in a circle. |
