Weightlifters have training programs to help them get stronger.

They lift weights that are heavy enough to strengthen their muscles.

Different weightlifters use different amounts of weights as they train.

What would happen to a weightlifter who only trained with small, light weights? They would never get any stronger!

What would happen to a weightlifter who only used weights that were too heavy to lift? They would not get stronger, only frustrated!

It’s important for a weightlifter to train with weights that are right for him.

Working out with AR is the same as lifting weights…

Reading only easy books will not make you a better reader.

Trying to read books that are too hard will not improve your reading.

Use the five finger rule!  Open the book to a full page.  Begin reading.  Put up a finger for every word you don’t know.  If you have all 5 fingers up before you finish the page, it’s too hard.

Reading books in your ZPD will help strengthen your reading!

You can always read books that are a little above or below your ZPD. You’re not locked into those levels.

Think of your ZPD as a ladder. You are “working out” to climb as high up as you can.
