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 slides for them to include in their
notebook. (SLIDE 7 & 8)
