Tammy and Sammy were both students in Mr. Morton's reading class. Mr. Morton wasn't too strict about deadlines, and Sammy took advantage of that. Sammy did all his homework in his other classes. But he never
bothered to complete Mr. Morton's reading assignments. He figured that he could complete them later. Tammy,
on the other hand, completed each assignment Mr. Morton had assigned every night. She had to stay up a little
later, but she knew that reading was the most important subject. She knew that if she learned to read well, then
she could teach herself anything. So she always worked hard in her reading class. When the end of the quarter
came, Tammy and Sammy had both planned on going to the Magic Castle amusement park. They were both so
excited. But then Mr. Morton called Sammy's mother to report Sammy's grade. She grounded Sammy and that
weekend was horrible for him. He stayed up until 2:00 AM each night, yet he still couldn't complete all the
assignments. Meanwhile, Tammy had a great time eating pizza at Enchanted Castle. After that she stayed up late
and watched movies. She enjoyed her weekend free of stress and pressure. At the end of the quarter, Sammy was
lucky to squeak by with a C minus. Tammy earned an A. Yet, Sammy still hasn't learned his lesson. He may not
complete this activity either.
