The document provides instructions for working problems on whiteboards and lists 10 multi-part math word problems involving writing equations of lines (WEL) given various conditions such as being parallel or perpendicular to other lines, passing through given points, or having a given slope or intercepts. Students are to write the equations of the lines on their whiteboards.

2. Boards Up Reminders
• Switch board with partner every problem.
• Only items directly related to math we are doing should
be on the board.
• Markers must be capped when not in use.
• Do not draw on the erasers.
• If you are not writing on the board, then you should be
working on the problem in your notes.
• Do not put the boards up until I say "Booarrddssss
Uuppp!"
• If you have questions ask your partner, before you ask
me.
