Public Practice Guide
Use this guide to see the type of reasoning MathRoutine expects for grade 1 comparison word problems 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.
Eli has 14 shells. Ava has 9 shells. How many more shells does Eli have than Ava?
Reasoning Strategy
Find the gap between the two amounts: 14 - 9.
AI Support Preview
Explain that 'how many more' asks for the difference, not the total.
Practice Ladder
Modeled after elementary workbook expectations: make the story structure visible before moving to the number sentence.
Read the story and identify whether quantities are being joined, separated, or compared.
Represent the situation with a drawing, number sentence, or missing-part equation.
Answer in a complete unit so the student connects the number back to the story.
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 subtracts in the order the numbers appear.
Likely diagnosis
Comparison language is not yet tied to larger-minus-smaller reasoning.
Next practice
Use 'how many more' and 'how many fewer' problems with matched diagrams.
If the attempt shows
The student reports what is left when the question asks what changed.
Likely diagnosis
Final-state and change-amount roles are being mixed.
Next practice
Practice start-change-end tables with the unknown in different positions.
