Public Practice Guide
Use this guide to see the type of reasoning MathRoutine expects for grade 7 inequalities 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 school club has at most $240 for a banner order. The design fee is $36, and each banner costs $18. What is the greatest number of banners the club can order?
Reasoning Strategy
Write 36 + 18b <= 240 and choose the greatest whole-number solution.
AI Support Preview
Make 'at most' and whole-number banners both visible.
A student needs at least 450 practice minutes this month. The student already has 165 minutes and plans to practice 35 minutes per day. How many more days are needed?
Reasoning Strategy
Model the remaining minutes with a greater-than-or-equal inequality.
AI Support Preview
Translate 'at least' as meeting or passing the target.
A ride requires riders to be more than 54 inches tall. Jordan is 51.6 inches tall and grows about 0.3 inch per month. After how many whole months can Jordan ride?
Reasoning Strategy
Solve 51.6 + 0.3m > 54 and round up to the first whole month that works.

Emphasize the strict 'more than' condition.
A theater group can spend at most $240 on costumes. Each costume costs $18 plus a $24 delivery fee. How many costumes can they buy?
Reasoning Strategy
Write 18c + 24 <= 240 and interpret whole-number solutions.

Show why the answer must be a whole number.
A student needs at least 420 minutes of reading this week. She already read 165 minutes. If she reads 45 minutes each day, how many more days are needed?
Reasoning Strategy
Model the remaining minutes with an inequality.

Explain 'at least' as greater than or equal to.
A ride requires passengers to be more than 48 inches tall. Kai is 45.5 inches and grows 0.4 inches per month. After how many months can Kai ride?
Reasoning Strategy
Solve 45.5 + 0.4m > 48 and round to the next whole month.

Focus on the strict inequality.
A class can spend at most $300. A bus fee is $75, and each ticket costs $15. What is the greatest number of tickets they can buy?
Answer
15 tickets
Reasoning Strategy
Write 75 + 15t <= 300 and choose the greatest whole number.
AI Support Preview
Tie 'at most' to the budget boundary.
A student needs at least 500 minutes of reading. She has 185 minutes and reads 45 minutes per day. How many more days are needed?
Answer
7 days
Reasoning Strategy
Use an inequality and round up to meet the requirement.
AI Support Preview
Explain why a partial day is not enough in this context.

Practice Ladder
Modeled after middle-school workbook expectations: combine fluency with ratio, percent, equation, and geometry reasoning rather than only isolated computation.
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 writes an equation for a situation with a range of possible answers.
Likely diagnosis
Limit language such as at most or at least is not being modeled.
Next practice
Use boundary-decision stories where several answers are valid.
If the attempt shows
The student rounds the boundary in the wrong direction.
Likely diagnosis
The algebraic boundary is not being interpreted as a whole-number decision.
Next practice
Practice greatest/least integer answer problems with budget or capacity limits.
Practice By Difficulty
Each level shows the reasoning load that level should demand, not just more of the same problem.
