Number Two Pencils have been the mainstay of writing forever it seems. The problem is that there are students who struggle with getting the pencil writing dark enough so that they can easily read what they have written. For these students there is a new technology alternative.
There is a truly erasable pen called the Frixion Clicker which is sold under the Pilot label. These pens do erase marks completely. Sometimes the issue is the quality of the paper on which a student is writing. The good news is that students can easily see what they have written. This is especially helpful in math. Students need to show the steps in their work to solving math problems. The darkness of the writing makes each step stand out from the page. This is something to consider using if the student has dyslexia, reading comprehension problems, or vision problems or just likes to see their work more easily.
