Transformations on a Grid
Mathematics · Geometry · procedural
Identify, describe, and represent the position of a shape following a reflection or translation using appropriate language; know that the shape has not changed
What mastery looks like
- Reflect a triangle in a vertical mirror line on a coordinate grid and state the new coordinates
- Translate a shape 3 units right and 2 units up and describe the movement
- Explain that a reflected/translated shape is congruent to the original
Check your understanding
If Transformations on a Grid slides or flips a shape on squared paper, can they describe exactly where it ends up and confirm the shape itself hasn't changed size or angles?
