Listen to or read "The Very Hungry Caterpillar"! The activities from speech-fun.com are great for working on vocabulary and spoken grammar skills right along with the story. Youtube has read alouds of this and many other stories. If you do not have a certain book at home, this is a great way to find a book!
Go to my previous post of "The Very Hungry Caterpillar Speech & Language Activities" to access the vocabulary and grammar activities.
The following link is a nice slide share of the book so your child can look for and practice using the grammar skills found in the book. https://www.slideshare.net/samanthamorris211/the-very-hungry-caterpillar-7574597
