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 4 Money Word Problems

Jay bought 3 notebooks for $2.35 each and a pen for $1.80. He paid with $10. How much change should he get?

Reasoning Strategy

Multiply the notebook price, add the pen, then subtract from $10.

Separate item cost, total cost, and change.

Example 2Grade 4 Money Word Problems

A jacket costs $48. It is discounted by 25%. What is the sale price?

Reasoning Strategy

Find 25% of the original price and subtract the discount.

AI Support Preview

Example 3Grade 4 Money Word Problems

Maya has $37 after buying a $16 ticket and a $9 snack. How much money did she have before the purchase?

Practice Ladder

How difficulty should build

Modeled after upper-elementary workbook expectations: start with accessible computation, then apply it inside a multi-step real-world situation.

Separate useful numbers from background details.

Choose the operation sequence before calculating.

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 retell the story in simpler words?

Does the student know which quantity is unknown before calculating?

Can the student check the answer against the question sentence?

Common Mistakes

What MathRoutine watches for

Using the amount paid as the cost instead of subtracting to find change.

Applying a discount as if it were the final price.

Rounding too early before cents are fully calculated.

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.
