Identify, describe and represent the position of a shape following a reflection or translation, using the appropriate language, and know that the shape has not changed

What this means, in plain words

Translating a shape means sliding it, without turning it or flipping it.

Shape work names shapes by their properties, sides, corners and faces, rather than by what they look like.

Representing means showing the same maths another way, with objects, a picture or a bar model, so the structure becomes visible.
