Artic. - /b/ /p/ medial position PICTURE match-up.
Find the matching pictures. They all have /b/ and /p/ somewhere in the middle of the word. If all the pictures don't show, use the "refresh" key. Say each word aloud as you practice. Have fun! Check out my ALL PICTURES class page at: http://www.quia.com/pages/allpicturesfun.html
