Print the following page as a SLIDE to get graphs for the students to glue in their foldables. If you don’t have glue you can have students draw a simple graph in their foldables. y x

Some useful tips about Foldables Once the foldable is done you must have the students USE it on a follow-up activity such as a short quiz, BINGO game, or set of guided practice problems or the students will NEVER use it. For grading purposes have students paper punch foldables to keep in their binder, put in their portfolio, or to hand in for a note-check. When making foldables it’s best to hand students just 2 or 3 different colored markers to make color changes to emphasize words or concepts but not so many that they get distracted. Always have at least one or two foldables cut out and ready for students who make mistakes. If a student is absent the day of the foldable then just print out the relevant Powerpoint slide for them to include in their notebook. (SLIDE 13)
