Learning is in sweet and steady stages. After your students learn to say the letters of the alphabet, the next step is to introduce them to small words. And, after they have mastered that, you must move on to constructing short and simple sentences. This easy worksheet will test how well your lessons have paid off, and if your students really understand how a sentence works. Ask them to read the sentences in this worksheet. Then, ask them to circle the correct word that starts the sentence.
