I scoured the Internet for some Kindergarten worksheets, mostly focusing on letter formation and sight words.
Letter Formation:

Sight Words:
I really like this sight word game, Roll A Sight Word. The worksheets are printed without words, so I am able to fill in the words that fit the class schedule, or the few that Amelia needs extra practice to master. You need one standard die and a pencil. Writing the sight words repeatedly is a fantastic way to soak in the spelling and help memorize the pattern and look of the word.
And finally, I made several worksheets of my own. Amelia loves to color, so I printed several sheets filled with bubble-letter sight words. I say the sight word, she colors it. This helps her to recognize the word, plus she has fun coloring. We have a few rainbow words around our house!
