I've been reading some research lately, and several people have mentioned the importance of having students connect to the parts of irregular words that they ARE able to sound out. Then you tell them the part they just have to LEARN BY HEART you can help them remember this by actually drawing a heart around the irregular portion of the word. I heard this wonderful idea in a dyslexia workshop with Dr. Nancy Mather. Hopefully, you're able to use it with your students!
