One of the few things I learned from my Kindergarten practicum (other than how not to treat students) was a game called BANG. It is a really simple game that helps children practice sight words (and I taught the children how to play it using math facts). In the game you have some sort of flash cards. Take a few of the cards (about one for every 5 or 6 cards) and put a small sticker on it. After that you are ready to play!
The rules of the game are simple: You move in a circle. Each child is shown a card. If they say the sight word (or give the fact etc.) they keep the card. If they get it wrong, the next person gets a try until the card is taken. When you get to a card that has a sticker, you get a "bang". If you are right, then you can take a card from another players pile--but only if you can say the word/ give the answer. Play until the cards run out. The player with the most cards win.
Fair warning...you may want to change the name of the game (or get ready to hold in your adult humor)... because you will her things like...
"I am going to bang you!"
"Stop banging me!"
"She is banging me again!"
