Pencil grip is just what it sounds like – the way you hold a pencil or pen (assuming, of course, that you received the coveted ‘pen license’ in primary school!).
This is probably going to be like that time your friend bought a new car and then all of a sudden you saw that car everywhere, but if you look around now, you’ll probably notice all kinds of pencil grips.
How kids hold their pencil is also a very common topic of discussion between teachers and parents because it really affects the quality and speed of their writing.
