Sample Problems

Problems should reveal how the student thinks

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.

Example 1Grade 6 Percent of a Whole Stories Word Problems

A school survey includes 240 students. If 35% chose art club, how many students chose art club?

Reasoning Strategy

Use 35% of 240 and keep the answer in students.

AI Support Preview

Mark 240 as the whole before calculating the percent.

Practice Ladder

How difficulty should build

Modeled after elementary workbook expectations: make the story structure visible before moving to the number sentence.

1

Separate useful numbers from background details.

2

Choose the operation sequence before calculating.

3

Explain why the final number answers the question that was actually asked.

Assessment Signals

What a strong attempt should show

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.

Can the student choose a structure without being told the topic?
Does the student ignore irrelevant details and keep the target question visible?
Can the student explain the first step before doing any arithmetic?

Common Mistakes

What MathRoutine watches for

Using the part as the whole.
Treating 15% as 15 instead of 0.15 of the whole.
Forgetting to answer in the story unit.

Learning Loop

The product value is the diagnosis after the attempt

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

The content is built to reveal the reason behind the miss

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 chooses an operation from a keyword instead of the situation.

Likely diagnosis

Operation selection is too keyword-driven.

Next practice

Use mixed-operation stories where the same keyword appears in different structures.

If the attempt shows

The student solves the first relationship but misses the final comparison.

Likely diagnosis

The final question is being lost after an intermediate result.

Next practice

Practice multi-step stories that require writing the target sentence before solving.
