Here is a complete set of first grade sight words for the year (over 220 words), broken down into groups for each month August - May. Many first grade words are part of the Kinder set of words, making this a great resource for kindergarten as well. Many students in second need additional sight word practice. This would make a fun and easy RTI activity.
Each set is in color or black and white for more economical printing. The "a" and the "g" that are used look like the ones the students learn to write.
In addition to the sight words, I've included directions on how to prepare and play BOOM! A Sight Word Game. Your kiddos will be giddy with excitement at the anticipation that the next card drawn might say "BOOM!" They will be engaged as they practice listening to, reading and saying their monthly sight words.
