Eureka Math Lesson 2: Translations
A sample lesson plan to explore mathematical translations
This lesson introduces the concepts of basic rigid motions using informal language and prior knowledge of length and angle measures. Students experiment with rigid motions of two-dimensional figures on and off the coordinate plane. This lesson specifically focuses on translations.
Students use a Never-Sometimes-Always graphic organizer to make sense of the properties of transformations they observe throughout the lesson. As they share their solutions, they understand that when figures are moved by a translation, length and angle measures are preserved. During the lesson debrief, encourage students to connect the idea that a translation is a type of rigid motion because length and angle measures are preserved.
