This resource is also available in Scottish Gaelic. Perfect for Gaelic learners! What is reflective symmetry? Reflective symmetry is where a shape or pattern is reflected in a mirror line or a line of symmetry. The shape that has been reflected will be the same as the original, it should also be the same size and it will be the same distance away from the mirror. What is Rotational symmetry? Shapes and patterns can have many different lines of symmetry. This all depends on how many times the shape can be folded in half, yet still remain the same on both sides. A circle, for example, has an infinite number of lines of symmetry because there are more ways of folding it in half than there are of counting. Other shapes, like a love heart, can only be folded in half one way.

Both preparing for and writing job applications contain elements of reflective writing. You need to think about the experiencethat makes you suitable for a role and this means reflection on the skills you have developed and how they might relate to the specification. When writing your application you need to expand on what you have done and explain what you have learnt and why this matters - key elements of reflective writing. 2.

An excellent activity for visual learners and KS1 Maths. Students going into Year 5 will be taught how to reflect shapes and patterns using an axis - they may be given half of the shape and to draw the other or, given the full shape and asked to reflect it over onto the other side. Engineers use reflection lines to judge a surface's quality. Reflection lines reveal surface flaws, particularly discontinuities in normals indicating that the surface is not C 2 {\displaystyle C

As well as teaching your child about symmetry, these challenge cards can be used to support the development of fine motor skills as well as visual coordination. This exercise will test their accuracy, focus and is an excellent, hands-on way for them to learn all about reflective symmetry and how it works.

For precise qualitative and quantitative analyses, all parameters were measured separately and independently by two retina specialists (SD, MAS) who were masked to the patients’ clinical details. If there were any discrepancies in the measurement of qualitative parameters, another investigator (PY) was consulted for the final decision. Statistical analysis When researchers are working on a project they will often think about they way they are working and how it could be improved as well as considering different approaches to achieve their research goal. They will often record this in some way such as in a lab book and this questioning approach is a form of reflective writing. 6. In academic writing If you're looking for a resource to help you teach about lines of symmetry, then why not try this Investigating Lines of Symmetry Worksheet KS2? When do children begin to learn symmetry? Reflective studs are a common sight on motorways and are designed to help drivers stay in the correct lane and improve visibility in poor weather or darkness.

White Use these differentiated worksheets to help your children develop their understanding of how to draw a shape reflected in a horizontal or vertical mirror line. Another important reason for using reflective studs on motorways is to help drivers spot upcoming changes in the road, so that they can adjust accordingly.
