Public Practice Guide
Use this guide to see the type of reasoning MathRoutine expects for grade 11 logarithmic scale models 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 sound model L(x) = log base 2 of (x - 3) reports L(x) = 5. What input x produced the report?
Reasoning Strategy
Convert the logarithmic statement to x - 3 = 2^5, then undo the shift.
AI Support Preview
Separate the log argument from the final input.
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.

Diagnosis Examples
Each word problem should create evidence about setup, calculation, vocabulary, hidden quantities, or final-question confusion. These examples show what MathRoutine is designed to separate after an attempt.
If the attempt shows
The student treats a parameter as an output value.
Likely diagnosis
The role of the parameter in the model is unclear.
Next practice
Use parameter-recovery problems with one given input-output pair.
If the attempt shows
The student ignores a domain restriction when using an inverse or trig model.
Likely diagnosis
Advanced-function constraints are not being checked.
Next practice
Practice inverse/trig stories where the valid branch is part of the answer.
