Reading longer words

Break it into parts, then say it fast

The short answer

How do I help my child read longer words?

A U.S. practice guide gives a routine for long words: find the parts the child already knows, say the parts, say them again fast, and check that the word fits the sentence. The child adjusts the vowel sounds as needed until the word sounds like a real word.

What the research found

  • 6 × Strong evidence
  • 1 × Expert advice, not a trial
  1. The guide says that learning common letter patterns lets a child read harder words by saying smaller parts of the word.

    In the source’s own words“Learning to recognize these patterns in words enables students to identify more complex words by pronouncing smaller parts of the word as they read.”
  2. The guide says to show children how to find meaningful parts inside a word, once they know a few common spelling patterns.

    In the source’s own words“Once students have learned a few common spelling patterns, show them how to analyze words by isolating and identifying meaningful word parts within them that share a similar meaning or use.”
  3. The guide gives a routine for long words that starts with circling the parts the child knows, such as beginnings and endings.

    In the source’s own words“Circle recognizable word parts. Look for prefixes at the beginning, suffixes at the end, and other familiar word parts.”
  4. In that routine the child says the parts, then says them again fast, then checks that the word fits the sentence.

    In the source’s own words“Say them again fast to make it a real word. revisiting, unhappiness 5. Make sure the word makes sense in the sentence.”
  5. The guide says children should adjust the vowel sounds as needed until the word sounds like a real word.

    In the source’s own words“When students read the word, have them adjust the vowel sounds as needed to achieve a recognizable word when said at speed.”
  6. The guide says knowing what word parts mean can also help a child work out the meaning of a long word.

    In the source’s own words“Students can also use their knowledge of the meaning of different word parts to infer meaning for a multisyllabic word.”
  7. The intervention guide says that in extra phonics help for grade 2, children also use their phonics on words of more than one syllable.

    In the source’s own words“Students also apply phonetic skills to words with more than one syllable.”

What this means at home

  • Cover part of a long word and let your child read one part at a time.
  • Point out common beginnings and endings as they come up.
  • Have your child check that the word makes sense in the sentence.
  • The free two-minute check points to what to work on first.

What the research does not tell us

  • On teaching word parts that carry meaning (morphology), the Castles review says it is not yet clear which way of teaching works best.
  • The review says one open question is when teaching about meaningful word parts in print should start.
  • The 'strong' rating is for Recommendation 3 as a whole; the guide does not rate the long-word routine separately.

How we write these pages

  1. We read the source itself, not a news story about it.
  2. Every finding on a page names its source and where in the source it is found, so you can check it.
  3. We say how strong the evidence is, in the words of the people who reviewed it.
  4. We say what the research does not tell us. Most studies are done in schools, and no study can say what one child needs.
  5. If we get something wrong, tell us at hello@sounditoutreading.com and we will correct the page.
