Many teachers find this set of half size picture cards easier to display when wall space is limited. Teachers frequently display the half size picture cards on the wall and use the full size cards when working with small groups or the whole class. This set contains both color and black and white versions of the characters. Teachers can display the black and white versions first and then cover each black and white character's picture with a colored picture when the character's lesson is taught. This way students can monitor their progress. The half size cards are also handy to use for sound manipulation and substitution exercises because they are easy to handle.
