This week we have been working on using a pointing finger to point to common/household objects (for example: "point to the yellow duck").  At home you can have your child point to household objects or to objects in books and practice using a good pointing finger.  Label what they point to and help them say the word if possible. 

This week in TLC we worked on our /k/, /p/, and /t/ sounds at the end of words (duck, sheep, boat...).  We read the book Duck in a Truck and played a game using items/activities that had our target sound in them.  
One idea to practice at home would be to have your child point (with a pointing finger) to objects around the house or in a book that have these sounds at the end of a word.  Model the word for your child and have them say it back to you.
