Ryder was in first grade. He couldn’t read long vowels yet. His peers surpassed him. They were reading sight readers like Frog and Toad while he was stuck on Kindergarten phonics books. Although he brought home long vowel worksheets, the long vowel patterns simply didn’t stick. He did oa ow worksheets one week and the next he couldn’t read glow, float or soap. What is going on? his parents wondered. They thought he might have a memory-deficit.

Interleaving is mixed practiced: weaving old phonics sounds into new lessons
Kids that struggle with reading need research-based instruction. The science is clear: research-based instruction includes interleaving. What is interleaving? In sum, interleaving allows kids to practice old material while learning new concepts. This ensures that students don’t guess, as they would if they completed oa ow worksheets with all the long o sound: toast, flow, moat, row, mow, moan…etc. Of course the child knows to say long o… all the words say long o!

In oa ow worksheets that only include oa ow words, the child simply memorizes that long o is in the middle. This does not facilitate learning that lasts. To make the phonics sounds actually stick, use interleaving in your lessons. For example, kids usually learn oa ow after learning some other long vowels. Thus, weave those other long vowel patterns into your lessons. Change your list from 1) glow, flow, row, float, mow to look more like 2) fond, glow, reef, Gail, moat…etc. In this second list, your student cannot guess.

- in the short-term, appears to hinder learning since it is more effortful.
- in the long-term, dramatically enhances retention.
- is an important part of research-based reading lessons.
