Students will get a card with a world problem on it. Students will determine the slopes and y-intercepts and line up silently in order from smallest to greatest values. This is a great and easy activity to get students up and moving around the room! This is also a great way to quickly assess students in their knowledge of slopes and y-intercepts without using a worksheet or quiz. This also would be great for either a warm-up or a wrap-up activity. I used this in my Algebra I and Math Models classes.
