Transformations on a Grid
Identify, describe, and represent the position of a shape following a reflection or translation using appropriate language; know that the shape has not changed
Suggested ages 9–10
Learning journey
Your child is learning to measure and work with angles using protractors, classify shapes by their properties, and understand transformations like reflections and translations while exploring how angles relate to each other.
Evidence of understanding
- 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
Assessment prompt
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?
