Savings Account: Simple Interest Growth Calculation

Grade 7Math2 days

This project for 7th grade students explores the concept of simple interest to help them understand the importance of savings accounts in achieving financial goals. Through activities like simulations and worksheets, students will learn how to calculate simple interest, understand the components of savings accounts, and assess real-world scenarios that affect savings growth. The project encourages students to engage in discussions, perform calculations, set up mock savings accounts, and analyze different financial factors to enhance their financial literacy skills.

Common Core State Standards for Mathematics

CCSS.MATH.CONTENT.7.RP.A.3

Primary

Use proportional relationships to solve multistep ratio and percent problems.Reason: This standard aligns with the project as it involves using proportional reasoning to calculate simple interest, which is a type of percent problem requiring multiple steps.

CCSS.MATH.CONTENT.7.EE.B.3

Primary

Solve multi-step real-life and mathematical problems posed with positive and negative rational numbers in any form using tools strategically.Reason: This standard is applicable because students need to solve real-world problems involving simple interest and savings growth, which involves multi-step calculations using rational numbers.

CCSS.MATH.CONTENT.7.NS.A.2

Supporting

Apply and extend previous understandings of multiplication and division and of fractions to multiply and divide rational numbers.Reason: Understanding how to multiply and divide rational numbers is crucial for calculating simple interest and understanding the growth in savings accounts.

Common Core Standards for Mathematical Practice

CCSS.MATH.PRACTICE.MP2

Secondary

Reason abstractly and quantitatively.Reason: The project requires students to reason quantitatively and abstractly when analyzing interest calculations and savings growth scenarios.

Entry Events

Events that will be used to introduce the project to students

Savings Simulation Game

Start the project with a classroom game that simulates saving money, earning interest, and managing expenses. Each student begins with a certain amount of 'money' and makes decisions that affect their savings over time, providing a dynamic introduction to the topic.

Activity 2

Savings Account Setup Simulation

Engage students in setting up a mock savings account where they apply their understanding of savings, deposits, and calculate simple interest over time.

Steps

Here is some basic scaffolding to help students complete the activity.

1. Provide students with an initial 'virtual' amount of money to deposit into a mock savings account.

2. Guide students to choose terms for their savings account such as interest rates and duration.

3. Ask students to calculate how much interest they would earn at the end of various periods using their chosen terms.

4. Encourage students to adjust their account terms and observe the effects on their interest earned.

Final Product

What students will submit as the final product of the activityA portfolio showing the setup of a savings account with calculations of interest over different terms.

Activity 3

Growth Factors Analysis Lab

Students investigate factors affecting the growth of their savings over time, including interest rate changes, additional deposits, and withdrawal scenarios.

Steps

Here is some basic scaffolding to help students complete the activity.

1. Introduce factors that can influence savings growth such as changes in interest rates, additional deposits, and withdrawals.

2. Guide students in conducting experiments by adjusting these factors in their mock accounts to see real-time effects on their savings.

3. Have students document their findings and share different scenarios and results with the class.

4. Facilitate a discussion on how these factors play out in real world banking and personal finance.

Final Product

What students will submit as the final product of the activityA report analyzing how different factors influenced savings growth in their mock accounts, supported by data and scenarios.
