Help with the homework, not the answers
Two kinds of app end up on a school phone. One photographs a question and returns the answer. The other explains the method and makes the child do it. Both have a place, and the difference between a useful evening and a wasted term is knowing which one is open. The honest version is that the scanners are excellent when a parent cannot remember how long division works, and corrosive when they become the first thing opened.
Help, and the other thing
| What the child needs | The kind of app | What to watch for |
|---|---|---|
| To understand a method nobody at home remembers | A solver that shows every step | Reading the steps rather than the answer |
| Practice at something already half learned | A drill or game with levels | Levels chosen by the app, not by the child |
| To memorise facts, dates or spellings | Spaced repetition or flashcards | A deck that is too large to finish |
| To see what is actually happening | A graphing or geometry tool | It is a tool, so it needs a question |
| To hand the work in | Whatever the school uses | School logins, not a better app |
| Someone to explain it | A video lesson | Watching instead of attempting |

What to install, by job
Photographs a maths question and shows a worked solution step by step, with an explanation of each line. The best of the scanners, and the one most worth supervising.
The same idea, free, with graphing and practice questions generated from the problem you scanned. Often clearer on algebra.
Covers a wider range of maths than either, up to calculus and statistics. Full steps sit behind a subscription.
Scans a question and finds explanations and videos rather than solving it outright, which suits subjects that are not maths.
A question and answer library with community answers. Genuinely useful for a stuck explanation, and the easiest of all of these to misuse. Supervise it.
Free structured courses from primary arithmetic to secondary science, with practice after each lesson. The closest thing to a curriculum on this list.
The version for ages two to eight, covering early reading and number work. No advertising, no purchases, and the quality is unusual for the category.
Maths practice wrapped in a game that children will open voluntarily. A paid membership adds cosmetics, which is worth knowing before the asking starts.
Times tables against the clock, used by a great many schools. It needs a school login, so it is only useful if yours uses it.
The alternative for tables with no account at all. Plain, fast and quietly effective for ten minutes a day.
Letter sounds and spelling for the earliest years, with voice prompts. Check the volume before handing it over.
Graphing, geometry and algebra in one, free, and the standard tool in a great many classrooms. The one app here a secondary student will still use next year.
The graphing calculator people actually enjoy using. Typing a function and watching it move teaches more than a page of plotted points.
Flashcards with shared decks for most common courses, which saves an hour of typing in vocabulary or dates.
The serious version of the same method, offline and free. Make a small deck of exactly what keeps being forgotten and review it daily.
Quizzes made by teachers and by anyone else. Good for revision as a game with two or three people in the room.
Not optional if the school uses it. Reviews are poor and it is still where the homework actually is, so set the notifications up properly and move on.
The parent side of a primary school portfolio, for schools that use it. Worth installing to see the work rather than hear about it.
When they are stuck and it is getting late
- Read the question back together, out loud A surprising share of homework failures are reading failures, not subject failures.
- Find one worked example of the same type Not the answer to this question. The same shape of question, solved, is what makes the next one possible.
- Do one line each, alternating It keeps them in the work instead of watching, and it shows you exactly where the understanding stops.
- Stop at a fixed time, and write a note to the teacher An honest note saying where it broke down is more useful to a teacher than a finished page they did not do.
- Put the thing they could not do into a flashcard deck Five cards reviewed daily for a week beats a second hour tonight.
Rough guide by age
| Age | What helps most | What to avoid |
|---|---|---|
| 4 to 7 | Phonics and number games, short sessions | Anything with an open internet connection |
| 7 to 11 | Tables drills and a reading habit | Answer scanners, for now |
| 11 to 14 | A solver that shows steps, supervised | Answer libraries used alone |
| 14 and up | Flashcards, graphing tools, past papers | Watching videos instead of attempting |
One more thing worth saying plainly to an older student: a photographed answer that nobody can reproduce in an exam hall is not revision. The scanners earn their place by explaining a method once, and lose it the moment they become the method.
One solver, supervised. One drill they will actually open. One flashcard deck of what keeps being forgotten. Read the steps back before writing anything down.
Frequently asked questions
Are answer scanning apps cheating?
The app is not, the use can be. Scanning a worked example to learn a method is study. Scanning the homework and copying the result is not, and it shows up at the next test.
Which single app helps a primary age child most?
One tables drill and one reading or phonics app, ten minutes each. Anything broader tends to be opened once and abandoned.
Do these need accounts?
The free course and flashcard apps generally do, to sync progress. The calculators and drills mostly do not, which makes them the better choice for a shared family tablet.
What about the school's own app?
Install it, however mediocre it is, because that is where the deadlines live. Just do not expect it to teach anything.
