the ones that i found in my desk this morning. but now i use felt tip pens like the one on the bottom right of this picture because ink cartridges have been a problem on airplanes and i travel a lot. (sometimes the air pressure makes ink cartridges leak all over me and once the security people took them out of my luggage because they said they looked dangerous.) i always travel with a small pack of pens and colored pencils so i can work anywhere.
i created a video to tell my high school students about some of the things they might write about in their notebooks. it is here.
