Teaching Consonant Blends and Diagraphs

I love to share lesson plans with other teachers and homeschooling parents.


What Are Consonant Blends and Diagraphs?

Certain letter combinations represent specific sounds, such as "fl, st, sw, gr, and bl." When these letter combinations are composed of consonant letters, they are called "consonant blends." These blends can occur anywhere in the word, but we will introduce them at the beginning of the word. We have a special name for letter blends where one letter is silent, but it changes the sound of the other letter, these are "diagraphs." Examples of diagraphs are "ch, th, and sh."

Initially, a child learns basic CVC words, or words comprised of the basic consonant-vowel-consonant pattern, like cat and dog. Once these are mastered, it is time to move on to beginning these words with consonant blends and diagraphs, like chat and frog.

So what about teaching consonant blends and diagraphs...

How is it done?

Up until this point, your child has probably been working on CVC words, or word families. These word families, have a common ending and number of possible beginning consonant letters. For example, the "AT" word family is comprised of words like "cat, hat, bat, rat, sat, mat, pat, and vat." Follow this link for more information on Teaching Word Families and CVC words.

Because your child is comfortable with the "AT" family, we can now introduce blends to the beginning of this family to easily help a child learn to blend letters. Common blend combinations for the "AT" family are:








The "UG" Word Family - Adding Consonant Blends and Diagraphs to the Beginning of this Word Family

We use flip books to practice word families. Begin by reading only the ending of the word, such as "UG." These flip books begin by adding single letters to the beginning of the word, for example, "bug." Then the book progresses to using blends such as, "plug."

  • slug
  • drug
  • snug
  • chug
  • thug
  • plug

These flip books from Lakeshore Learning are used to teach children a variety of words with the same ending spelling, by flipping the page to change the beginning of the word only. In the photo, it shows more difficult words, but the kit begins with the basic "at," "ag," etc. families explained here and words it's way to more difficult word endings. Each flip book begins with single consonant letter beginnings to each word and moves to adding consonant blends at the beginning of the word later in the book.

Explode the Code Book 2

"Get Set for the Code" and "Explode the Code"

This book series actually begins with "Get Set for the Code" A, B and C. These books teach basic letter sounds. When a child completes this series, they move on to the "Explode the Code Series." Book 1 and 1 1/2 are for exploring CVC words. Book 2 is the first book that includes letter blends, and diagraphs. Book 2 1/2 is for further exploring these words and are for kids that want a little extra practice beyond book 2.

When I bought the Leap Pad I thuohgt it was a bummer because it did not come with this book although it was shown on the cover of the box. However, once I learned that this book was available I purchased it.My just turned five year old pre-schooler has not put it down since I bought it two weeks ago. He works hours at it. Never tires. His progress has been spectacular. My wife who taught phonics for 30 years is very pleased not only with the book but the way it teaches phonics. My pre-schooler has not only learned his phonics but he is beginning to read.I have had difficulty getting him interested in other Leap Pad learning books but not with this one. He thirsts for knowledge and this Leap Pad product has really turned him on.I would highly recommend it for children who have already learned their alphabet and are beginning to write. The only drawback is that it way too expensive.

Love this. Where were you when I was homeschooling our three boys? :) Nice job!

Barbie Crafts from United States on October 20, 2011:

Your child is a lucky, fortunate child to have a parent so interested in them. Thanks!

Peggy Hazelwood from Desert Southwest, U.S.A. on October 20, 2011:

Very good information, Heather! I think the games with the flip cards would be so helpful in teaching this.
