The listing, Laminated Number writing practice has ended.
This is how I taught my children how to write their numbers 1 through 20. The numbers 1 through 10 are not laminated but are inside of sheet protectors. I used dry erase markers to let them practice over and over the formation of these numbers. Numbers 11 thru 20 are laminated. Again, I used dry erase markers on them. I'm sure you can also use washable markers but I haven't tried it. Each piece of paper is front and back so you are looking at, in the pictures, the front side then the backside. My only tip about using dry erase markers is that the longer the ink sits on top of the laminated sheet the more permanent the dry eraser becomes. So washing it off or wiping it off as soon as possible is the best way to go about it.
