DS5 does HWT with his OT. The school does "trace this letter 40 times" method. They have not been at the same spot all year (school goes ABC order, HWT goes their own order). The letters covered by HWT are so much clearer. It really works for my kid.

I bought the teachers guide, the workbook, the tray and dough letters, the wood letters with the cards and mat, the little chalkboard, the big chalkboard, the tiny pencils, the chalk, the crayons, the iPad app and the tiny sponges. So yeah, I went a little nuts with it. I justified it with he is my oldest and the stuff is high quality so I can use it again with DS2.

One thing to keep in mind is that all of the extra stuff covers only uppercase letters. The workbook and teacher guide covers upper and lower case.
