Lesson Details

Key learning points

Coordinates are recorded in brackets with the numbers separated by a comma.
Count along the x-axis and then the y-axis to find the coordinates for the marked point.
The shape made with the new points after translation should be exactly the same shape and size as the original shape.

Common misconception

Pupils might write the y-coordinate (vertical distance) first instead of the x-coordinate (horizontal distance).

Reinforce the correct order by teaching "x comes before y" just like in the alphabet. Practice with examples and devices like "along the x-axis, then up the y-axis" to solidify this concept.
