Practice the Literacy Links Alphabet Song with me daily! For the first few times please encourage your child to do exactly what I do and sit next to them to ensure they are practicing it correctly. Also, feel free to pause the video and try to correct speech sound errors but only do it with the video so that your child does not feel that they are always being "corrected".
A great way to teach your child correct speech sounds during daily activities is to listen to what they have to say and then rephrase it with emphasis on the appropriate speech sounds. For example, your child says, "I lied that" but means "I like that" emphasis the /K/ sound in "like" and use varied inflection in your voice saying, "I know you like that!"
Have a great summer!
