This pack includes the High Frequency Words for the First Grade Reading Street Common Core Edition. These are the words for the ENTIRE reading series (including Unit R).
There are a number of ways you can use this: as an assessment tool, as a sticker book, a homework assignment or any other way you can come up with.
I use it as an incentive "Star Book." Each student gets a book at the beginning of the school year. When individual students can read and write each word, he/she places a star sticker inside the star besides each HF word. When students complete a week and all their stars are filled in, they are able to pick from the "Star Box."
