This is a spelling test I use to see if students have learned the spelling pattern 'th' digraph. After the phonics lesson, I have the students fold over the spelling words to the back. I administer the test. Students then unfold the words and self-correct. Any word that is misspelled, they spell correctly along the line 3 times.
You can use the Google Doc link to make your own copy and then change words that might not be the best fit for your students.
In this spelling practice worksheet, students will look for 1-3 misspelled words per sentence and then rewrite them correctly on the line. This is an emphasis on the 'th' digraph.
