There are many ways of teaching 3rd grade high frequency words. Other than drilling, which is great for a short time, you can play all kinds of word games.
If it is wintertime, you can play Melting Snowman. This is the opposite of Hangman; as you draw two snowmen with the same number of parts, from 10-14. Each team member that gets a word right gets to erase one part of the opposing team's snowman. If it is not winter time, you could draw other things, like animals, flowers, or trees.
Worksheets and puzzles are also a way to teach high frequency words. Even a simple alphabetizing worksheet with the Dolch sight words would expose the students to the words more. One kind of puzzle that the students really enjoy is a word search. There are sites online where you can make your own to print out and use. Two of them are Word Search Fun and Puzzlemaker.
