Use this Smartboard file to review letter sounds as well as uppercase/lowercase matching.
Have students take turns clicking one die to get a letter. Then have them write the uppercase letter to match the lowercase letter on their die. Make it harder by having them say the name of the letter or the letter sound.
Make it easier by only having students say the name of the letter or by coping the lowercase letter.
This is a great activity for those days when you have 5 or 10 extra minutes. It's quick to get started and can last as long or as short as you need it to.
Use ABC Dice as a literacy center also!
