The first grade Houghton Mifflin series introduces a chunk of High Frequency Words every week. This booklet is a great way to keep track of which words your students know, as the year progresses. Put the booklets together and start assessing! You can have volunteers quiz your students weekly with the flashcards. Then, you can put a sticker (or laminate and use dry erase markers for reuse next year!) next to each word the student knows.
For these booklets, I used:
