Warming up the muscles before writing is a very important stage. Before starting to work on letter formation, joins or pre-handwriting patterns it is a good idea to help focus the body on the activity that it is about to be performed in a fun and relaxed way.
The exercises only take a couple of minutes to do. Not only can they be done at the beginning of the session but throughout and at the end to help relax muscles and release tension that may build up over the session. Tense muscles can make handwriting difficult and make a child tire more quickly.
