While we eat dinner, someone will say a letter and everyone has to think of things we can eat that start with that sound.

"b, b, bananas!"
"b, b, brocolli"
"b, b, brownies"
And then my little one gets silly and says something like "b, b, books!" Hey, at least he recognizes the sound!
We will also get them guessing about their dessert. "Your surprise starts with the sound like C."
"candy?!"
"cupcakes?!"
"cauliflower?!"
This helps with sound recognition, yet they think it's just fun!
What sound games do you play at home?
