This is a game to review Patterns on Earth (Day/Night Cycle, Shadows, Seasons, Tides, and Moon Phases).. Students will form a 3x3 Shape by matching vocabulary words with definitions(same idea as dominoes). Included in the file are 2 versions of the game. There is a more difficult level for higher performing students. Not all words and definitions will have a match. The words and definitions on the outer edges do not have a match. The 2nd version can be used to differentiate for struggling or SPED students. All words and definitions will have a match. There is not text on the outer edges of the games. You may want to instruct students the pictures on each card are related to all physical properties and are not intended to be clues to the words and definitions on that particular card. I would laminate the cards for durability. I would also print 2 of each card to have one for the answer key. Also available in a bundle with all of my 3x3 review games. Also available as a part of my 3x3 Review Game Bundle.
