# Spaced repetition for kids: a review schedule that fits a school week

> How spaced repetition works for children, what classroom studies found, and a 1, 2, 4, 7 and 14 day word review schedule you can run at home.

Spaced repetition for kids means reviewing a new word a few times, with a longer gap before each review: the next day, two days later, four days after that, then a week, then two weeks. Each review takes a minute or two. Children remember more of what they learn this way than when they practice the same words many times in one sitting, and the extra cost is a little planning, which a box of cards or an app can do for you.

This guide explains why the gaps help, what studies with young children found, and how to run a five-step schedule at home with paper cards or with the flashcards in Wordventure.

1. **Pick a small batch.** Choose five to eight new words your child met today, ideally things they can see in a picture or in the room.
2. **Keep the misses.** Ask for each word once. Words your child cannot name or spell go on a card with today's date.
3. **Review the next day.** Show the picture side and ask for the word before turning the card over. Keep it short and cheerful.
4. **Stretch the gaps.** Each time a card is answered, wait longer before it comes back: two days, then four, then a week, then two weeks.
5. **Restart the slips.** If a word is forgotten, it goes back to a one-day gap. Nobody loses points; the card simply returns sooner.

## What spaced repetition means for a child

Most children learn a new word in the same way: they hear it, connect it to a thing, and then lose it within a few days unless it turns up again. Spaced repetition plans for that loss. Instead of drilling *giraffe* ten times on Monday, a child meets it on Monday, again on Tuesday, again on Thursday and again the following week. Each meeting is a small act of recall, and recall after a gap is harder work for the brain than recall a minute later. That extra effort is what makes the word stick.

For a four-to-eight-year-old, the shape of each review matters more than the exact dates: a picture, a pause, and the child saying the word before anyone says it for them. A review where a parent reads the word and the child repeats it is rehearsal. A review where the child has to pull the word up from memory is the thing that works.

## Does spaced repetition work for young children? What the research shows

Most research on the spacing effect was done with adults, but several studies have tested it with school-age children, and the results point the same way.

- **Year 1 reading lessons.** Seabrook, Brown and Solity (2005) asked two teachers of Year 1 classes (mean age five and a half) to teach the same phonics material for two weeks. One class had three 2-minute sessions a day; the other had one 6-minute session. The total time was the same. Children taught in short, spread-out sessions improved by 8.3 points on the phonics measure, against 1.3 points for the single-session class.
- **Five to seven year olds learning science.** Vlach and Sandhofer (2012) gave 36 children aged five to seven science lessons on a massed, clumped or spaced schedule. Spacing the lessons out produced better generalization, for both simple and complex concepts.
- **Ten year olds learning vocabulary.** Sobel, Cepeda and Kapler (2011) taught fifth graders the meanings of eight uncommon words in two sessions, either a week apart or back to back. Five weeks later, the spaced group recalled roughly three times as many meanings as the massed group, after the same amount of teaching.

A large review by Cepeda and colleagues (2006) pulled together 317 experiments on spaced practice. One finding is useful for parents: the best gap between reviews gets longer as the time you want to remember the material gets longer. That is the reason a good schedule starts with short gaps and stretches them out, instead of using the same gap every time.

None of these studies tested the exact schedule below, and none of them prove that one set of gaps is the best for every child. They support the general pattern: short sessions, spread out, with gaps that grow.

## A spaced repetition schedule for kids

The schedule below starts with a first look on the day a word is saved, then reviews with gaps of one, two, four, seven and fourteen days. It is the same pattern Wordventure uses for saved flashcards. If your child saves a word on a Monday and remembers it every time, the reviews fall like this:

*Review schedule for one word saved on a Monday, when every review is answered correctly*

| Review | Gap since the last review | Day it comes back | Time it takes |
| --- | --- | --- | --- |
| First look | None | Monday (day 0) | Under a minute |
| 1 | 1 day | Tuesday (day 1) | Under a minute |
| 2 | 2 days | Thursday (day 3) | Under a minute |
| 3 | 4 days | Monday, week 2 (day 7) | Under a minute |
| 4 | 7 days | Monday, week 3 (day 14) | Under a minute |
| 5 | 14 days | Monday, week 5 (day 28) | Under a minute |

Notice how little time this takes. A child who adds six new words a day will never have more than a small pile due on any one day, because most cards are spread across the coming weeks. If the pile starts to grow, add fewer new words until it shrinks.

Weekends are fine to skip. A card that is a day or two late still benefits from the gap; the risk is a card that sits untouched for a month and has to start over.

## Spaced repetition flashcards on paper: the box method

You can run the schedule with index cards and a shoebox split into five sections. This is often called the Leitner box, after Sebastian Leitner, who made the method popular.

- Draw or glue a picture on the front of each card and write the word on the back. Children aged four to six do better with a picture prompt than with a written one.
- New and forgotten cards go in section 1, which you check every day.
- When your child names a card correctly, it moves one section to the right. Section 2 is checked every two days, section 3 every four, section 4 once a week and section 5 every two weeks.
- When a card is forgotten, it goes back to section 1. Say the word together, then move on.
- After section 5, the card is retired. Keep a jar of retired cards so your child can see the pile grow.

The weak point of paper is the calendar. It is easy to forget which section is due, and a box that sits on a shelf for two weeks loses most of its value.

## How Wordventure schedules flashcards for you

In Wordventure, children learn words by tapping things in painted scenes of a [small town](https://wordventure.web.app/#places): the zoo, the supermarket, the kitchen at home. At the end of a round they see a summary, and any word they missed can be ticked to keep as a flashcard. From then on the app tracks the dates. Each saved word is due the day it is saved, then comes back at gaps of a day, two days, four, a week and two weeks, and every two weeks after that. A word your child does not know yet starts again the next day.

The flashcards list shows what is coming up: a lion and a giraffe due today, a toothbrush tomorrow, a sofa in three days, an apple in a week. Your child does not need to know the schedule exists. They open the app, review the few words waiting, and go back to exploring. Progress and flashcards sync through iCloud, so a review started on an iPad continues on an iPhone. You can read more about [how the flashcards work](https://wordventure.web.app/#flashcards) on the homepage.

## Mistakes that make spaced repetition stop working

The schedule is simple. Most problems come from the way each review is run.

### Showing the answer too soon

Give your child three or four seconds of silence before helping. Saying the word for them turns a recall into a repeat, and repeats do much less.

### Adding too many words at once

Twenty new cards on a Saturday become twenty cards due on Sunday, twenty on Tuesday and so on. Five to eight a day keeps the daily pile small enough that a review stays a game.

### Using words with nothing to picture

Early on, pick concrete nouns: things a child can see and point to. The [first words list grouped by place](https://wordventure.web.app/articles/first-words-list-for-kids) is a good source, and the [picture vocabulary activities](https://wordventure.web.app/articles/picture-vocabulary-activities) guide has games for the first meeting with a word, before it goes into the box.

## Questions parents ask

**What if my child misses a few days of flashcard reviews?**

Pick up where you left off. A card that is a few days late still benefits from the gap. If your child cannot recall a word after a long break, send it back to the one-day gap and let it climb again.

**How many new flashcards should a young child add each day?**

Five to eight new words a day is a comfortable start for children aged four to eight. If the number of cards due each day keeps rising, add fewer new words until the daily review fits in a few minutes again.
