I had prepared Handwriting examples for the class using the font Jarman. If you prepare all your handwriting lessons like this then you will always have them available. I have created them in PowerPoint. They can then be projected onto the screen for the children to copy out. Modelling how the letters are written can be done over the projection or on another whiteboard. I also like to have an individualised handwriting programme for my students so the separate PowerPoint slides can be printed out and laminated so you have class sets of the cards.
