Introduce algebra as a similar concept but using letters as part of mathematical notation
they will become more familiar with in high school
Hand out video worksheets and introduce video. Students fill out worksheet as they watch
Hand out algebra challenge worksheets to students to complete.
Go through answers and introduce homework/extension activity
