Class Topics: 09.23.13

In Common Core Math Six today, students in 1, 3, and 4° reviewed their quizzes from Friday.  Mr. Giomini modeled some problems dealing with scientific notation since that caused students some issues on the quiz.  Lesson 2.5: Greatest Common Factor was introduced and practiced by students in class.  Word problems such as the one below were discussed to model the application of the skill.

At a display booth at an amusement park, every visitor gets a gift bag.  Some of the bags have items in them as shown in the table below.  Which visitor will be the first to receive a bag with all three items?
