Lesson Details
Key learning points
- Move the point in the horizontal direction in the translation.
- Move the point in the vertical direction in the translation,
- The shape made with the new points should be exactly the same shape and size as the original shape.
Common misconception
Pupils might mistakenly alter the shape or size of the polygon during translation, thinking the process involves resizing or reshaping.
Emphasise that translation is a "sliding" motion that moves the shape without changing its size or orientation. Demonstrate this with cut-out shapes that can be physically moved on a grid, showing that the shape remains identical after translation.
Keywords
Vertex / vertices - A vertex is the point where two or more lines meet. The plural is vertices.
Translate - Translation is a transformation in which every point of a shape moves the same distance in the same direction.
