Coordinates (age 12+)
Understand similarity as a relationship where one shape is an enlargement of another; construct similar shapes by enlargement with a given scale factor and centre, with and without coordinate grids
Teaching approaches
Gakuva’s recommended starting approach is selected. You can still compare every option.

If your child wants to enlarge a photo so it's three times bigger, can they work out the new dimensions — and explain that the shape stays the same but all lengths increase by the same factor?
