Interactive Grade 6 worksheet where students analyze 10 weeks of school water usage, calculate gallons saved, compute percent decreases, and complete a ratio table to track a conservation campaign. Auto-graded.
Maplewood Middle School has launched a 10-week Water Warriors campaign to reduce campus water usage. In this interactive Grade 6 worksheet, students step into the role of junior data analysts for the school's Green Team. They work through real conservation data — calculating how many gallons were saved each week, computing percent decreases from a baseline, and expressing savings as simplified ratios.
This worksheet makes ratio and percent concepts feel meaningful by grounding them in an authentic environmental context that middle schoolers care about. Watching a live line chart update as they enter their percent calculations gives students immediate visual feedback on the campaign's progress — turning abstract numbers into a compelling data story.
Assign this worksheet after students have been introduced to percent of a whole and writing part-to-whole ratios. It works well as a culminating application activity for the 6.RP.A unit.
In this worksheet, students will calculate the gallons of water saved each week by comparing weekly usage to a Week 1 baseline across a 10-week conservation campaign. Students will compute the percent decrease from baseline for each of the nine campaign weeks and enter those values to populate a dynamic line chart that visualizes the school's conservation trend.
Students will interpret the full data set and articulate what the numbers reveal about the Water Warriors campaign's success in a written reflection. By the end of the worksheet, students will demonstrate fluency applying percent decrease and ratio concepts to a real-world environmental data context.
This worksheet supports randomization — each student receives a unique Week 1 baseline water usage and weekly usage values, all designed so that percent and ratio calculations always produce clean whole numbers. The structure, questions, and grading rubric stay identical for every student, making it easy to review and discuss as a class while preventing answer sharing. Would you like to enable randomization for this assignment?
💡 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.
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 →Find a percent of a quantity as a rate per 100 (e.g., 30% of a quantity means 30/100 times the quantity); solve problems involving finding the whole, given a part and the percent.
All 6.RP.A.3c activities →Summarize numerical data sets in relation to their context, such as by:
All 6.SP.B.5 activities →More interactive, auto-graded activities on the same standards and topics.

Interactive Grade 6 worksheet where students use tape diagrams to solve 6 ratio problems in real-world contexts - finding parts from totals and unknown parts from known parts. Auto-graded with randomization support.
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.
Step into the Smoothie Shop and simplify real-world recipe ratios! Students practice reducing fractions to lowest terms using the greatest common factor (GCF). Perfect for introducing or reviewing simplifying fractions through a fun, food-based context.
Students will analyze dot plots representing real-world data, such as the ages of students participating in a school carnival. They will answer questions based on these plots. Each student will receive three unique sets of data and questions, encouraging individual analysis and critical thinking.
