D: Word Patterns (or word families)

One of the most common ways to teach using phonics is through the use of word patterns. Word patterns are sets of rhyming words such as run, fun, bun and nun. By using vowel sounds in a context such as this, it is easier for learners to understand the sounds they make and apply this knowledge to new words. Generally, this is a much easier method than studying and applying the rules of phonics for vowel sounds!

Who is this intended for?

You can use word patterns with all levels, but it is generally more popular at the beginning levels.
