Big Ideas: Numbers, expressions, and measures (for example lines and angles) can be compared by their relative values. Two- and three-dimensional objects with or without curved surfaces can be described, classified, and analyzed by their attributes (for example the size of their angles and sides). Objects in space can be oriented in an infinite number of ways, and an object’s location in space can be described quantitatively. Objects in space can be transformed in an infinite number of ways, and those transformations can be described and analyzed mathematically. Students will be able to apply a translation to an ordered pair and be able to explain that the resulting new image is congruent to the original pre-image. Vocabulary: congruency/congruent, similarity, transformation, translation, reflection, rotation, parallel, image, prime, congruent, notations, order pair, proper labels and symbols, pre-image, angle, line Special Materials: Graph Paper Rulers Protractor Geo boards Patty Paper Geometry Software
