Master core mathematical concepts through our interactive Socratic curriculum.

This hub is for students who need free percentages practice that shows the reasoning, not just the answer. It groups 30 browser-based missions around reasoning about parts per hundred and percent change, aligned with 6.RP.A.3.C.
The companion guide explains it as: Find a percent of a quantity as a rate per 100; solve problems involving finding the whole, given a part and the percent.
Practice Goals
Common Mistakes
Use Cases
Use after ratios and unit rates.
Ask what represents 100 percent in the problem.
Complete one mission, then say what changed, what stayed the same, and why the final answer makes sense.

Everything you need to know about the Socratic experience.
There are 30 missions in this topic — 10 Seedling (entry-level), 10 Explorer (core), and 10 Challenger (stretch). Each mission has 3 Socratic steps with adaptive hints.
This topic is aligned with CCSS 6.RP.A.3.C. Open the topic guide for the standard's full text and a step-by-step breakdown of the cognitive sub-skills.
Start with Seedling missions to anchor the visual model, then move to Explorer for the core abstraction, and tackle Challenger only when Explorer is flawless. Difficulty badges on each card show this progression.
Three big shifts: numbers extend to negatives; arithmetic becomes letters; and equations become problems to *solve*, not just check.
Ratios are the multiplicative version of addition: instead of asking 'how much more?' we ask 'how many times more?'. This thinking is the entry to slope, similarity, and proportional reasoning.
Research on "productive struggle" shows that 20–60 seconds of focused effort BEFORE help dramatically improves long-term retention — the brain encodes the strategy more deeply. Inquiry AI's hint timing is calibrated to this window: short enough to prevent frustration, long enough to lock in the learning. Parents can adjust the threshold in settings if a learner needs faster scaffolding.
Yes. Every mission, handbook page, and topic hub is mapped to a specific CCSS code (visible in the page header). The curriculum follows the CCSS coherence map: Grade 1 number sense → Grade 3 multiplicative thinking → Grade 6 ratio reasoning, with each grade building strictly on the prior year's foundations.
