Why your child understands math homework but fails the test

By Ran Bian, founder of ROH Tutoring

Homework checks whether a student can recognize how to solve a problem when they have time, notes, and examples nearby. A test checks whether they can recall the method alone, under time pressure, with other topics mixed in. Students who do well on homework but poorly on tests usually have a recall problem, and it can be fixed.

Why it happens

Recognizing a method is easier than recalling it. Right after a lesson, the method is fresh and the homework matches the example. On a test, nothing tells the student which method to use.
Notes and examples carry a lot of the work. Many students look back at the example for every problem, and without it they can’t get started.
Tests mix topics. Homework usually practices one skill at a time, so choosing the right approach on a test is a separate skill.
An older gap slows them down. Trouble with negative numbers, fractions, or distributing can cost just enough time to leave questions unfinished.
Test anxiety. One hard problem early in a test can throw off the rest of it.

What helps

Redo two homework problems the next day with the notes closed.
Practice short sets that mix problem types, since tests mix them too.
Have your child explain out loud how they would start a problem and why.
Look for an older gap. A short diagnostic often shows one pre-algebra skill behind many current mistakes.
Do a timed practice set a few days before the test.

When to get help

If grades haven’t improved after a few weeks of this, or your child avoids math homework altogether, a tutor can usually find the specific gap quickly. ROH Tutoring starts with a free 15-minute call and a diagnostic session, followed by live sessions on Zoom. We tutor everything from elementary math through algebra and AP Calculus, online for families in Walnut and beyond. See pricing.

Questions

Common questions

Does this mean my child is bad at math?

No. This pattern is very common, and it usually comes from how a student practices.

Should they do more homework problems?

More of the same problems won’t help much. A few problems done without notes, with different types mixed together, build recall better.
