Hi I am new to Kindergarten this year. Some teachers suggested I use the thick beginner pencils for students who still can't hold a pencil well. I don't like them and I don't know how much they help since I've never used them before. Some of my students have their own pencils and they're the regular pencils. The problem with the thick ones is the eraser/top always come off. Also I don't know how to sharpen them. I've only been able to replace them so far because the teacher before me had a lot of them pre-sharpened. Which do you prefer to use?
