Kindergarten High frequency words as taught in Harcourt Trophies series, along with color words and number words. These words are printed large and outline, so you can laminate them and use them in literacy centers with playdough, wikki sticks, or stickers to reinforce words. I have used popcorn stickers before, as we call them 'Popcorn words' at my school. I have also had kids use highlighters to color them in... they had fun 'buttering' their popcorn words! You could also use bingo dobbers to have students color the words in.
