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 y draw a simple graph x in their foldables.

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.
