Sounding out and reading coaching leads to success

While reading about how sounding out and reading coaching is an effective tool for early readers I got to thinking about how important these skills are for later on. Teaching young children to use pictures and letter sounds to decipher a word is the basis of using context clues to better comprehend literature later on.This skill can be developed in many different ways but one way that seems really effective is worksheets that have both pictures and words and the student has to decide what word goes where(context) and sound them out(phonetics). For example if a student can read the first sentence on the worksheet on right they can practice using pictures and sounding out to put in the correct word. These can be practiced using general cues like what do you know about trains? That way the student better figures out the answer without  too much prompting. I think on of the most important parts of what Cunningham reading said was basically just because you can sound out a word doesn't mean you know what it means. A worksheet like the one below could definitely help see if I child is just sounding out or if they understand what the word says. A student working on number one

may be able to read the word bag but only if they possess the correct vocabulary will know the word is supposed to be log.

Discussion Question: Do you think theses activities could help with coaching?
What other ways can we make sure students are receiving the right amount of assistance(and right type)?
