Public Practice Guide
Use this guide to see the type of reasoning MathRoutine expects for grade 10 function transformations 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 sensor model starts as f(x) = x^2. A new calibration uses g(x) = 3(x - 4)^2 + 6. What output does the new model give when x = 10?
Reasoning Strategy
Apply the horizontal shift inside the input, square, stretch, then shift the output.

Force the order: inside change before output changes.
A company models daily demand with f(x). A promotion shifts demand 2 days earlier and raises every output by 150 units. How should the transformed model be written?
Reasoning Strategy
Represent an earlier input shift inside the function and the output increase outside.
AI Support Preview
Connect earlier timing to an input transformation, not a vertical shift.
The graph of y = |x| is compressed vertically by 1/2, shifted right 3, and shifted down 4. What is the transformed equation?
Reasoning Strategy
Place the right shift inside the absolute value and the vertical changes outside.
AI Support Preview
Check each transformation against input versus output behavior.
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.
Connect the equation form to the real situation before calculating.
Evaluate, reverse, or compare the model while tracking restrictions and units.
Use the result to answer the actual question, not just the algebraic expression.
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.
