This is a coordinate plane activity that includes plotting points in all 4 quadrants to make a lava lamp. I have spent many years perfecting these pictures using input from my students. There is a circle to identify the origin and I have made every 5th line darker which makes it easier to see and easier for the students to quickly find the locations.
Teaching is a career change for me. I spent almost 20 years in the engineering field. I am now going into my 9th year of teaching math in the middle school.
