24 rainbow sets that are meant to be separated for students to match and build compound words. Each rainbow set is embedded with a tiny picture that not only match each other but match the compound word so that students can check their work with a magnifying glass for correctness. This set comes with two different background options, plain white and a fun St. Patrick's Day chevron. It is recommended that this activity be printed on card stock and laminated for durability, and each rainbow is framed with an easy-to-cut outline or you could cut the rainbow itself out if you prefer to remove the background altogether. This activity can be used as it is for a fun matching activity, or you can use it in your St. Patrick's Day sensor bin for an exciting twist. I hope you and your students enjoy this activity and happy teaching!
