These printable picture rhyming cards from Prekinders are a great way to practice rhyming!
This specific printable is made for matching the rhyming pictures but when I printed them I was thinking of presenting it to B like they do in between shows on Noggin/Nick Jr. He loves those little games. They say something like “Which word rhymes with cat? Bat or rat? That’s right cat and bat sound the same. They rhyme.”
