Students act as the CEO of a company, to find the cheapest country to purchase the raw materials, students will do unit conversion between different currencies.
Real-World Math Worksheet on Currency Conversion, Ratios, and Unit Rates
Step into the shoes of a global CEO in this engaging, real-world math worksheet! In the Global Manufacturing – Raw Material Cost Comparison activity, students take on the role of a decision-maker in an international company, comparing the cost of raw materials sourced from Japan, the UK, and Germany.
Using provided currency exchange rates, students will convert prices from Yen, Pound Sterling, and Euro to USD. Then, they’ll analyze and compare unit rates to determine the most cost-effective supplier for each material.
This hands-on math activity reinforces essential 6th and 7th grade Common Core standards around:
real-world math worksheet, currency conversion worksheet, ratios and unit rates 6th grade, 7th grade math activity, global sourcing math activity, math worksheet on unit rates, compare prices using currency exchange, interactive math worksheet for middle school
Students will apply mathematical reasoning to convert between international currencies, compare unit costs, and identify optimal purchasing decisions based on real-world data.
They will practice using division and proportional reasoning in the context of global supply chain analysis, reinforcing skills in unit rate conversion, decision-making, and data interpretation.
If randomization is enabled, every student will get a different price to convert. This ensures that students can't just copy answers and helps individualized learning.
💡 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.
Fluently add, subtract, multiply, and divide multi-digit decimals using the standard algorithm for each operation.
All 6.NS.B.3 activities →Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities. *For example, "The ratio of wings to beaks in the bird house at the zoo was 2:1, because for every 2 wings there was 1 beak." "For every vote candidate A received, candidate C received nearly three votes."*
All 6.RP.A.1 activities →Understand the concept of a unit rate a/b associated with a ratio a:b with b ≠ 0, and use rate language in the context of a ratio relationship. *For example, "This recipe has a ratio of 3 cups of flour to 4 cups of sugar, so there is 3/4 cup of flour for each cup of sugar." "We paid $75 for 15 hamburgers, which is a rate of $5 per hamburger."*
All 6.RP.A.2 activities →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*.
All 7.EE.B.3 activities →Solve real-world and mathematical problems involving the four operations with rational numbers.
All 7.NS.A.3 activities →Compute unit rates associated with ratios of fractions, including ratios of lengths, areas and other quantities measured in like or different units. *For example, if a person walks 1/2 mile in each 1/4 hour, compute the unit rate as the complex fraction ^1/2/1/4 miles per hour, equivalently 2 miles per hour*.
All 7.RP.A.1 activities →Recognize and represent proportional relationships between quantities.
