Visit http://www.3minutemaths.co.uk/gcse-practice-papers/ Grade A*, A and B for GCSE practice questions. This video is all about enlargement by a negative scale factor and forms part of the playlist 'enlargement by negative scale factors.' The question is based on a series of GCSE enlargement by negative scale factor questions that can be downloaded here: This particular question asks for triangle A to be enlarges by a scale factor of -1.5 through 0 (the centre of origin). In this case I've used 'lines of enlargement' to draw the new shape accurately.

The evil Scaleo has escaped from prison and is transforming the length, width, and height of objects until they become useless... or dangerous. Who can put things right? Our super heroine, Scale Ella, uses the power of scale factor to foil the villain. Scale Ella addresses number and operations standards and the process standard, as established by the National Council of Teachers of Mathematics (NCTM). It guides students in: Using factors, multiples, prime factorization, and relatively prime numbers to solve problems. Developing, analyzing, and explaining methods for solving problems involving proportions, such as scaling and finding equivalent ratios.

In particular, you'll now learn to do everything with negative numbers (we're talking everything--adding, subtracting, multiplying, dividing, fractions, decimals... everything!). You'll also take your algebraic skills to new heights by tackling two-step equations. 7th grade is also when you start thinking about probability (which is super important for realizing that casinos and lotteries are really just ways of taking money away from people who don't know probability) and dig deeper into the world of data and statistics. Onward! (Content was selected for this grade level based on a typical curriculum in the United States.)
