Transformations Starters:Dice Reflections: A dice is reflected in two mirrors. What numbers can be seen? Mirror Maths: The bottom half of some symmetrical calculations are shown above. Can you work out the answers? Reflective Cat: On squared paper copy the drawing of the face then reflect it in three different lines. Rotational Symmetry: Draw a pattern with rotational symmetry of order 6 but no line symmetry. Wrapping Paper: Find the order of rotational symmetry of the repeating pattern.

Curriculum for Transformations:Year 5Pupils should be taught to identify, describe and represent the position of a shape following a reflection or translation, using the appropriate language, and know that the shape has not changed. more... Year 6Pupils should be taught to draw and translate simple shapes on the coordinate plane, and reflect them in the axes more... Years 7 to 9Pupils should be taught to identify properties of, and describe the results of, translations, rotations and reflections applied to given figures more... Pupils should be taught to identify and construct congruent triangles, and construct similar shapes by enlargement, with and without coordinate grids more... Years 10 and 11Pupils should be taught to interpret and use fractional {and negative} scale factors for enlargements more... Pupils should be taught to {describe the changes and invariance achieved by combinations of rotations, reflections and translations} more... Pupils should be taught to sketch translations and reflections of the graph of a given function more... Pupils should be taught to describe translations as 2D vectors more... Pupils should be taught to apply addition and subtraction of vectors, multiplication of vectors by a scalar, and diagrammatic and column representations of vectors; {use vectors to construct geometric arguments and proofs} more... Exam-Style Questions:There are almost a thousand exam-style questions unique to the Transum website. Feedback:Comment recorded on the 24 May 'Starter of the Day' page by Ruth Seward, Hagley Park Sports College: "Find the starters wonderful; students enjoy them and often want to use the idea generated by the starter in other parts of the lesson.
