Learning Intention:
- students analyze and investigate the translation, rotation, and reflection of geometric shapes
I Can:
- investigate translation, rotation, and reflection of two- and three-dimensional shapes
- describe geometric attributes of two- and three-dimensional shapes in various orientations
- recognize the translation, rotation, or reflection of shapes represented in artwork
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, we explored decomposing shapes to build our foundational understanding of geometry as we learned about slides, flips and turns. Students used critical thinking to break abstract shapes apart in different ways
▶ ▶ ▶ ▶ ▶ ▶ ▶ ▶ ▶ ▶ ▶
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) ▲ ▶ ▲ ▶ ▲ ▶ ▲ ▶ ▲ ▶ ▲ ▶ |
rotation (or turn): a transformation in which a shape turns about a stationary turn centre; it changes orientation but not size or shape
