'tr' Blends Spelling Test for Phonics

This is a 20-word 'tr' phonics blend spelling test.  Students take 5 minutes to study the words, next they fold the spelling list back on the line, then the spelling test is administered, students unfold the words, self-check, and then write the words they missed a few times on the line.  A Google Doc version is also linked in case you want to change any of the words to customize it.
