![]() ![]() Transform the image using a translation.Draw a shape on the grid which is not symmetrical.Be sure to subscribe to get the notification once it has been posted. I did something similar for Rotation, Translation and Enlargement (I will be posting these in the next few weeks). When the student goes home, hopefully, every time they look in the mirror they understand the mathematical concepts behind it. With Mathematics in Context, you want the student to tap into the knowledge they already have to understand a mathematical concept. In hindsight, I would have either had an image with its reflection and asked my students to look at it and tell me what they see, rather than me asking the directed questions above. The original object and the reflected object face in opposite directions.Īt the end of the session, I asked him to write the things he learnt from the tutor session on his book, without consulting the textbook.A point and its image are the same distance from the mirror line.To fully describe a reflection you need to state the mirror line (also known as the line of reflection).The image size and shape stays the same (congruent shapes).What do you need to be able to see your reflection?įrom this, I was able to explain that with Reflection:.What happens when you go forward or backwards?.Is the distance between you and the mirror the same as the mirror and reflected image?. ![]() What is the relationship between the direction you are facing and the direction your reflection is facing?.Look at the image again, which part is at the front?.Is the image the same size (using a standard mirror)?.Think about when you look at yourself in the mirror. Previous Knowledge needed: x and y-axis, coordinate grid, x and y coordinates, equation of a line. Well, there are four sub-topics a student needs to know about Transformations: The other day I was trying to explain Transformations to him and started with Reflection. I have been learning a lot from the one-to-one tutor. He is going to be sitting for his GCSE Mathematics exam in the summer. I was teaching reflection to my student who I tutor on Saturdays. ![]()
