Public Practice Guide
Use this guide to see the type of reasoning MathRoutine expects for grade 11 precalculus word problems. The goal is not worksheet volume; it is helping students read the situation, choose a model, and explain why the answer fits.
What Students Practice
Reasoning Patterns
Sample Problems
These grade-specific examples show the kind of student-visible reasoning MathRoutine is designed to support: identifying the important quantities, choosing the right structure, and checking the final answer against the story.
A rational model R(x) = k / (x - 4) + 6 gives output 14 when x = 8. What is k?
Reasoning Strategy
Use the distance from the asymptote first, then undo the vertical shift.
AI Support Preview
Separate the denominator value from the vertical shift before solving.
A sinusoidal signal has maximum 28 and minimum 10. What is its amplitude?
Reasoning Strategy
Find the vertical spread and divide it by 2.
AI Support Preview
Show why amplitude is half the max-min distance, not the full distance.
A polar checkpoint has rectangular components 6 and 8. What is the squared radius?
Reasoning Strategy
Use x^2 + y^2 to connect rectangular and polar representations.
AI Support Preview
Keep the squared radius distinct from the radius.
Practice Ladder
Modeled after Algebra 1/Algebra 2 workbook expectations: interpret a function or equation in context, solve or compare it, then justify the meaning of the answer.
Translate the language into a mathematical relationship.
Solve while tracking constraints, units, and intermediate quantities.
Check whether the solution makes sense in the original context.
Assessment Signals
A guide is useful only if it clarifies what teachers and parents should look for in student work. MathRoutine tracks these signals during practice instead of treating every miss as the same mistake.
Common Mistakes
Learning Loop
A strong word problem platform should not only say right or wrong. It should notice the pattern: missed unit rate, ignored leftover, reversed comparison, wrong base percent, or equation setup error.
