Welcome to "Fuel Mix Ratio", a 6th Grade Ratios mission at the Explorer (core) level, staged in our space exploration scenario. The mission opens with a hands-on prompt: "Build the simplified ratio 2 : 3 as a two-bar tape diagram (the simplified form of 8 : 12)." You'll reason about the numbers 2, 3, 8 across 3 guided steps.
Behind the space exploration story, this lesson is really about ratios aligned to CCSS 6.RP.A.1. Understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities. The key strategy this mission asks you to internalise: Simplified: 2 : 3.
A general pattern to watch for in 6th Grade ratios — illustrated with example numbers below, which may differ from this lesson's: Forgetting that ratios are scale-invariant. 2:3 and 4:6 describe the SAME relationship. Reduce or scale up, but the underlying ratio is one thing. If you get stuck on "Fuel Mix Ratio", the adaptive Socratic hints below escalate from a gentle nudge to a worked-out strategy — the same way a one-on-one tutor would coach you through it.

This explorer · core practice mission uses a tape diagram to move from the story to a precise ratios idea. Work through the prompts in order: notice the structure first, name the quantities, then check whether the final answer fits the original situation.
In 6th Grade Ratios, students need to connect the story, the model, and the symbolic answer. The core move here is: Simplified: 2 : 3. A useful check is to ask whether the answer avoids this pitfall: Subtracting instead of comparing multiplicatively. "Twice as much" (×2) is a ratio. "5 more than" is a difference. Different operations.
