Select three Tier Two vocabulary words to teach your students. A list of suggested words appears below. Write the vocabulary words on the board or on chart paper.


1. Introduce the story.

Today we are going to read a story entitled The Secret Science Project That Almost Ate the School.

2. Introduce the three vocabulary words you have chosen.

Before we read the story, I want to introduce some new words that we will come across. Please repeat each word after I say it.

3. Read the story.

Let’s read the story. Make sure to listen for today’s vocabulary words and to think about how they are used in the story. If you hear a vocabulary word while I am reading, raise your hand.

4. Define key vocabulary words. See definitions below.

Let’s think about our vocabulary words. The word ______________ means ____________. Does anyone remember how this word was used in the text?

Call on students to answer the question. Then refer to the text to show how the word was used in context. Repeat this process for each vocabulary word.


Now let’s practice what we’ve learned.


Brag means to talk a lot about yourself and how good you are. What’s the word?
