Big Bieber: If the dimensions of an object double, its volume increases by a factor of eight.
Middle of Centres: Find the midpoint of the line joining the centres of enlargement.
Star Wars Day: Estimate the size of an alien given the size of their hand. This could be an introduction to scale factors.

"We all love your starters. It is so good to have such a collection. We use them for all age groups and abilities. Have particularly enjoyed KIM's game, as we have not used that for Mathematics before. Keep up the good work and thank you very much

"Love using the Starter of the Day activities to get the students into Maths mode at the beginning of a lesson. Lots of interesting discussions and questions have arisen out of the activities.
Comment recorded on the 19 October 'Starter of the Day' page by E Pollard, Huddersfield:
"I used this with my bottom set in year 9. To engage them I used their name and favorite football team (or pop group) instead of the school name. For homework, I asked each student to find a definition for the key words they had been given (once they had fun trying to guess the answer) and they presented their findings to the rest of the class the following day. They felt really special because the key words came from their own personal information."
Comment recorded on the 26 March 'Starter of the Day' page by Julie Reakes, The English College, Dubai:
"It's great to have a starter that's timed and focuses the attention of everyone fully. I told them in advance I would do 10 then record their percentages."
When areas and volumes are enlarged the results are far from intuitive. Doubling the dimensions of a rectangle produces a similar shape with four times the volume! Doubling the dimensions of a cuboid produces a similar shape with eight times the volume!
Similar Shapes: Questions about the scale factors of lengths, areas and volumes of similar shapes.
Transformations: Draw transformations online and have them instantly checked. Includes reflections, translations, rotations and enlargements.
Enlargement by a scale factor: A Maths teacher goes through the idea of enlarging a shape from a centre of enlargement.
Enlargements: How to enlarge a shape by a positive scale factor and a centre of enlargement. Includes a scale factor less than 1 and a centre of enlargement inside the shape.
