Enlargement (A) allows pupils to practice enlarging basic shapes by positive integer scale factors, with and without a centre of enlargement.
In section A, students will enlarge a cuboid, a triangle and an ‘L’ shaped hexagon by two different scale factors each. Giving learners a chance to see variations of scale factors with the same polygons and practice enlargement of shapes with vertical and horizontal edges before progressing.
Next, in section B, the same shapes are enlarged by the same scale factors but this time from a given centre of enlargement; opening up a chance for discussion of “What’s the same? What’s different?”. We have included centres of enlargement that are on and off the objects so students can again notice the difference between the two and teachers/parents can introduce and discuss invariance in enlargement.
