These slides were made for a second grade Letterland lesson. They coincide with Letterland Unit 23 (ore, oor, and our words). You should go over these slides with the students as a review of the words. These slides are interactive. Each slide contains a picture and a clue. The students are to try to guess the word. Move the colored shape on each slide to reveal the answer. I normally used this before the students took their spelling test. You can conduct the review, or you can have the students come up to the board and move the shape to reveal the word.
