I created a flip chart to use with my class as I introduce the proper way to form letters. The sequence of letters begins with letters that have vertical and horizontal lines, then it moves to circular letters, then on to downward curves and finally diagonals. Last I have a section I use with only some students that focuses on specific lines, straight, horizontal, up and down with corners, curves.
There are four letters on a page because I have my children take turns with the pen or using dual pen mode so two can go at a time. I hope this helps instruction in your classroom as it has for mine!
