Target Skill #1 - Sequence What is sequence? Sequence of events is the order in which they take place, from first to last. Clue words such as first, next, and then may show sequence, but not always. Other clues are dates and times. Two events can happen at the same time. While and at the same time are clue words that indicate this.

Let’s Practice! Some of the most amazing inventions have not come from expensive laboratories. They have come from children your age! One of the most delicious inventions in the world came from an eleven-year-old named Frank Epperson, who in 1905 created the first frozen fruit bar. First, Epperson made a fruit drink for himself. Instead of finishing it, he left his drink outside overnight with a stick in it. Then, temperatures in San Francisco dropped to below freezing, and the drink froze. The next morning, he discovered that he liked the taste of the frozen fruit drink. Epperson couldn’t apply for a patent to claim ownership of the invention until much later, because at that time he was too young. He waited many years, until he was an adult, to patent the treat. Later, Epperson sold the idea to a company, which then produced the treats that you find in the store today. What happened after the temperatures in San Francisco dropped to below freezing? What year did Epperson create the first frozen fruit bar? When did Epperson patent his invention?
