On this worksheet, students must help Sam the Spider. He's caught a lot of bugs in his web, but he only wants to eat the bugs that have the letter blends "sp" and "st." Students must circle the bugs with words that have either "sp" or "st in them, in addition to writing an "sp" and "st" word at the bottom of the page. This activity is great phonics practice; it helps build vocabulary, and students get to practice spelling words with these common letter blends.
