It is important to keep your card parts consistent colors. This is a good support for all students but benefits English Learners in particular by offering a visual cue to assist with the vocabulary. Another strategy for supporting English Learners is to use pictures with the subject and predicate cards.

We sometimes call this type of simple sentence a kernel sentence. Simple sentences are like popcorn kernels that need to expand. When heat is added to a popcorn kernel, it expands and pops open. The kernel is just the start!

We can expand a kernel sentence to make it longer and more elaborate. Expanding sentences helps our readers understand our ideas better and picture them in their minds more clearly.

This is a good place to work on vocabulary by defining elaborate. When something is elaborate it has detail. Using the simple sentence The cat sleeps, you could compare a black and white clip art picture of a cat sleeping to a colorful picture of a cat with more detail.

Today we are going to learn one way to expand our simple sentences. We will do this by answering one or more key questions: When? Where? Why? or How? This allows readers to create a clearer picture in their minds of the action in the sentence.

When we have a simple sentence such as The cat sleeps, it does not tell us much about the sleeping cat. We need to expand our simple sentence to help the reader create a clear picture in their mind of what else we would like to communicate.

Our simple sentence tells us the who and the what. Who is the sentence about? The cat. What is the cat doing? Sleeping. But this simple sentence leaves the reader wanting to know more. We can make a clearer picture in the reader's mind by expanding this sentence.

Answers to these questions add detail. Where does the cat sleep? When does the cat sleep? These details will make a clearer picture in a reader's mind.

The simple sentence: The cat sleeps with the questions "where" and "when" below.
