My students love to Roll & Color, and with interchangeable dice (see the link below!) it is an easy and fun way to practice meeting and exceeding standards. This document includes roll and color recording sheets for letters A-Z (capital AND lowercase) as well as letter cards to stick inside the dice. If you don't have the dice, you can always write the letters onto cardstock and tape over dice you already have!
I use similar dice in my classroom http://www.amazon.com/Constructive-Playthings-Photo-Stacking-Blocks/dp/B002S3RW62/ref=sr_1_2?ie=UTF8&qid=1409180648&sr=8-2&keywords=picture+cubes
