I can investigate translation, rotation, and reflection of 2D shapes and 3D objects.
I can recognize the translation, rotation, and reflection of shapes in art.

Grade 2 Math
In Grade 2, students are initially introduced to the concept of transformations using the more familiar language of slide, flip, and turn. In later grades they will learn and use the more formal language of translation, reflection, and rotation.
This week, students learned about flips and slides, but first, we explored decomposing shapes to build our foundational understanding of geometry. Students use critical thinking to break abstract shapes apart in different ways:
When we were ready to learn about the movement of shapes, we used geo-boards to practice getting our slides and flips just right before moving on to paper.
translation (or slide): a transformation in which a shape slides to a new position without changing size, shape, or orientation

| Slides (translations) |
reflection (or flip): a transformation in which a shape is flipped across a line of reflection to form a mirror image; it changes orientation but not size or shape
 |
| Flips (reflections). We use 'Miras' (geo-mirrors) to help see images reflect onto a surface |

Next week, we will learn about rotations then look closely at art to see if we can find transformatons of shapes.
rotation (or turn): a transformation in which a shape turns about a stationary turn centre; it changes orientation but not size or shape
