These word of the week cards are meant to give families a specific word each week to focus on producing correctly. Choose a word with the student's speech sound in the target position (initial, medial or final) and write the word on this little pocket card.
I find that families are so busy and homework sheets for speech are the bottom of the list with all of the other homework students receive, even the young ones! This is a simple request and easy to do all week long! The theory is that if the student is reminded all week for his or her sound in one word, her or she is thinking about that sound and is likely to carry over that production into other words he or she is using.
I have had great responses from parents who like to keep the card in the car somewhere they can see it and remind themselves to listen for that word.
This works best if you choose a commonly used word or a word that appears regularly within that child's day.
