Paint Mixing Studio: An Interactive Equivalent Ratios and Ratio Tables Worksheet for Grade 6

Make equivalent ratios something students can see. In Paint Mixing Studio, your 6th graders run the paint station for a giant school hallway mural. Every color has a recipe card written in parts, such as Meadow Green at 2 parts blue to 3 parts yellow. Students scale each recipe to the exact amount of paint each part of the mural needs.

The twist is that the math makes the color. When students press Mix the Paint, their amounts are blended into a live color swatch next to the target color. An equivalent ratio produces a perfect match. If a student adds instead of multiplying, or scales only one part, the paint comes out visibly wrong. Students get instant, visual feedback on proportional reasoning, and nobody has to give away the answer.

The finale: Design Your Own Color

Students invent a brand-new paint with sliders for blue, yellow, red and white, watch the color change as they mix, and name their creation. When they press Finalize my Recipe, a customer places an order for that paint. Students then work out the scale factor and the exact cups of each color to fill it. Every student’s order is different, so the final problem is personal, creative and impossible to copy.

What students practice

• Finding a scale factor and using it to scale a part-to-part ratio
• Completing ratio tables with missing values in any column
• Splitting a total amount into parts (part-to-whole reasoning)
• Scaling with a non-whole scale factor (half cups)
• Working with three-part and four-part ratios
• Fixing an incorrect mixture by working out how much paint to add
• Creating their own ratio and scaling it to fill a real order

Inside the worksheet

• 10 problems that build from simple scaling to multi-step reasoning
• Six recipe cards students look up as they work
• Live color swatches and a part-by-part mix bar, a visual model that also supports color-blind learners
• Auto-grading with a green tick beside every correct answer
• Randomized numbers for every student, which helps reduce copying
• A story-driven student introduction that sets up the mural mission
• About 25 to 30 minutes of focused practice, ideal for a full class period, small groups or homework

Standards alignment

• CCSS 6.RP.A.3: Use ratio and rate reasoning to solve real-world and mathematical problems
• Supports 6.RP.A.1 (ratio language) and 6.RP.A.3a (tables of equivalent ratios)

Perfect for

• Introducing or reinforcing equivalent ratios in 6th grade math
• Real-world and project-based math lessons
• Middle school math intervention and test review
• Teachers looking for engaging, no-prep digital ratio activities

When the colors match, students know their math is right. Paint Mixing Studio turns ratios from numbers on a page into a recipe they have to get right.
