In the word bank delete the "words" and add your own words. Then down at the bottom add the words in the word search and then fill it in with other letters. You can also change the title if your're not doing high frequency words.
The students will unscramble the words and write them on the lines under it. Then they will find the words in the word search at the bottom.
(The thumbnail looks like the title is not in the right spot, but when I open the file the words are where they are supposed to be.)
