Vectors and Transformations

On the other pages in this section we have divided our activities in to sub-topics. This page has them all together in one place for browsing

congruent halves

Brand Symmetry

Time 1-2h: Students use their knowledge of equations of lines to rebuild well known, symmetrical logos from a small fragment of the image. They then find and/or make their own logos, providing for their partner only a small fragment (using FREE photo editors such as paint.net, gimp or others) from which to rebuild the original.

 Escher Symmetry

Time: 2h. Observing symmetrical objects comes quite naturally to students because we are surrounded with symmetry.  Here’s an activity that takes that skill a giant step further.  A great example of how the use of computer software can create a whole new type of activity, this investigation gets students to analyse the symmetry in Escher tiling patterns by reflecting, rotating and translating them using Geogebra

Geogebra is dynamic geometry software that can be downloaded for free.  For this activity it is fairly intuitive, so even students new to it will have no problems.  There is a help video provided should technical assistance be required. 

This is a great example of how beautiful images, from the Artist Escher, can provide instant engagement for students.  Scaffolding is provided to help guide students through the early parts of this investigation, and some real challenges are posed at the end where a good deal of creativity and critical thinking will be required.

Symmetry patterns like these can be described in terms of rotations or gyrations, reflections, translations, glides and glide reflections.  Apparently differently looking symmetry patterns can have the same symmetry properties and there are 17 different wallpaper groups of symmetry in total.  Six of these groups are analysed in this investigation, but, if inspired, students could be encouraged to take this further and find and describe them all.  Inspired by this work, a recent student of mine wrote a research paper about all the different symmetries.

Parking Rotations

Time 1-2 hrs: This activity gets students to investigate the effect of changing the centre of rotation. It starts with a series of fun games in which the students have to park a car in a garage by giving the correct rotations.

Rotation Navigation

Time: 1h. When describing rotations, students often forget that coordinates define a centre of rotation. Through the designing and playing of the “Around the World” and “Jungle Obstacle” games students get lots of experience of defining rotations in a fun and creative environment. The software forces students to consider angle and direction and displays the coordinates of the centre of rotation. Lots of scope for extension challenging able 14-15yr olds as a starter activity.

Rotation Reflections

Rotation Reflections & Proof

Time 1-2hrs: A really nice investigation that requires students to apply and make links between a range of topics. Can students find a single rotation that has the same effect as two reflections? Can they formulate a general theory that works given any two reflections? Can they prove it!

Equation Reflections

Time: 1-2hrs Students often think reflection is easy, but the big change at this level is the need to define, using equations, the position of the mirror line. This activity uses Geogebra and/or Autograph to explore points on different lines to remind students why lines can be defined using equations. Three further
activities oblige students to use equations to perform reflections and create a reflective, art masterpiece!

Transformation Game

Time 30 mins to 1 hr: This is a fun board game to be played in groups of 2-4. Students use cards to transform a shape and gain points according to where they land on the board. This can be used as a consolidation activity for reflections, rotations and translations. Lots of fun guaranteed!

transformations and tessellations

Dr Who

Time: 1 hr+. This is a really absorbing and engaging puzzle that is rich with interesting mathematical behaviour. The essential learning objective for this activity is about scale factors of enlargement and repeated enlargement. The medium for the challenge really appeals and this type of dynamic question represents a whole new genre of questions that are offered by technology... 

The image of space as the backdrop and the effect of disappearing down a tunnel are really cool and makes students really want to be able to do it for themselves. To do so requires some critical mathematical thinking and problem solving. Students have to piece the observations together to make coherent explanations of what is happening and why it is happening before they can recreate it and it is here that the richness of this activity lies. I do seriously recommend that teachers try this for themselves before looking at the solution and discussion screencasts found in the teacher notes! Its great fun and an excellent challenge!

Dancing Vectors

Time 2 hrs. Introduce vectors through dancing! This is a great fun and effective activity where students imagine displacement vectors as dance moves! The vectors are combined to make a dance routine. Get the whole class up and dancing this routine to Donna Summer's hotstuff! It is a memorable experience and really helps students get to grips with this concept.

Vector Translations

Time: 1hr An introduction to the concept of vectors or for teaching translation. Students use arrow diagram vectors to reconstruct a picture and also record the vector in column format. They can then use Autograph or Geogebra to make their own challenge for a partner to reconstruct. The activity closes with a freekick, vector shoot-out applet.
