This document contains all 40 (plus a few extra!) high frequency words from the Kindergarten Scott Foresman Reading Street series.
Directions: On the first page, color in each popcorn word a different color. I usually do rainbow colors. Then, pass out both sheets to the students. The students will then have to read the sentences, find the popcorn words, and color over the popcorn words with the color that matches the box on top. On the second sheet, the students will rainbow write their words. I let the kids either pick crayons or markers and practice writing each word in the row of boxes across from the word!
