Possible Directions:
First two pages:
1. Copy enough for all students (not back-toback)
2. Go through the example as a whole class,
having students fill out the notes page as you
go.
3. With the two practice problems, you can
complete it as a whole class or give time to
try the two problems independently or with
partners.
4. Have students cut both pages out and glue
them into their notebooks.
Extra Practice Sheet:
Can be assigned for homework or in-class
practice, or given as an assessment.
Thanks!
