Students will use the simple interest formula and its variations to find the interest, principal to be deposited, and the interest rate they should be looking for to get $100,000 after 10 years for their dream house.
Teach students how math connects to real life with this engaging, real-world worksheet on Simple Interest. In this activity, students take on the role of someone saving for the down payment of their dream home—a goal of $100,000 in 10 years. As they work through three types of problems, they’ll gain valuable financial literacy skills while practicing key 7th grade math standards.
This worksheet includes:
Students apply the formula I=P×R×T in multiple ways—reinforcing proportional reasoning, percent applications, and basic algebraic manipulation. The real-world scenario keeps students motivated and helps them see why math skills are essential for smart money decisions.

The learning objectives are:
If randomization is enabled, each student will receive a different set of interest rates to work on. This helps prevent copying of answers.
💡 Tip: When assigning this activity to your classroom, you can optionally enable randomization to give each student a unique version of the problems. When you re-assign the same worksheet, each student will get a new set of questions, helping them master the content through repeated practice.
Solve multi-step real-life and mathematical problems posed with positive and negative rational numbers in any form (whole numbers, fractions, and decimals), using tools strategically. Apply properties of operations to calculate with numbers in any form; convert between forms as appropriate; and assess the reasonableness of answers using mental computation and estimation strategies. *For example: If a woman making $25 an hour gets a 10% raise, she will make an additional 1/10 of her salary an hour, or $2.50, for a new salary of $27.50. If you want to place a towel bar 9 3/4 inches long in the center of a door that is 27 1/2 inches wide, you will need to place the bar about 9 inches from each edge; this estimate can be used as a check on the exact computation*.

Students will use the simple interest formula and its variations to find the interest, principal to be deposited, and the interest rate they should be looking for to get $100,000 after 10 years for their dream house.
In this real-world math challenge, students use percent skills to shop smart at a tech store. They apply discounts, markups, and sales tax to build a tech bundle within a $150 budget, developing proportional reasoning and financial literacy.
In this Thanksgiving-themed math worksheet, students convert ingredient quantities into standard units and calculate the cost of preparing a holiday meal. It’s a real-world activity that strengthens unit conversion, proportional reasoning, and budgeting skills.
A real-world budgeting challenge where students apply rational number operations—decimals, fractions, and percentages—to stay within a $75 back-to-school budget.
The activity revolves around the concept of baking a Christmas cake on a tight budget compared to the cost of purchasing one from a store. Students will be guided through ingredient conversions, cost calculations, and the joy of creating a homemade treat.
Students analyze real-world financial situations to calculate percent increase and decrease. Using a connected storyline, students examine changes in stock investments, monthly expenses, and online store prices. This worksheet builds proportional reasoning through table-based problems and supports randomized values for independent, auto-graded practice.
