Pre-Writing.
It all begins with shapes. If your child is having difficulty writing their letters, then they might need to work on their pre-writing strokes first. Here are some worksheets to focus on before you jump into letters.
Letters
Once your child is getting good with pre-writing strokes now you can move on to letters! I would suggest starting with just the letters of their first name, and then moving on from there. Also start with all capitals, then move onto lower case.
Resource Handouts
Free handouts that include both pictures and information made to give you an easy to understand overview of a specific topic. These can be useful for parents, teachers, therapists, and even to give to other family members/friends to explain difficult topics.
