Linking maths to the inspiring realm of space exploration, the fascinating field of micro-biology, the exciting pursuit of sports performance or the compelling virtual worlds of gaming and digital media seems to come less instinctively. During a recent school visit I was sitting in the staffroom when the head maths teacher entered, having just finished a class with some Year 12 Advanced Mathematics students.

They were investigating an area of Cartesian geometry and trigonometry using complex numbers an area of mathematics which I will readily admit is beyond my expertise. Context in maths for children and young adults is especially critical. Added to this mental impediment to engagement for children is the highly abstract nature of pure mathematics. I never plan to visit there. This point was reinforced for me in a recent conversation that took place in our office.

The Celsius scale is based on heat or cold, relative to the freezing point of water. H2O is a molecular arrangement that is common on planet Earth and in certain other unique environments in the cosmos. It is, however, by no means the most abundant molecular arrangement in the universe — this status is enjoyed by H2, or hydrogen. As organic beings on our small blue-green planet, we like water as it is important to us.

Scientifically speaking, temperature is the amount of thermal energy emitted by atoms. If we are describing an atmospheric temperature of Applying the mathematics, this simply means we take How cold is this in terms of degrees Celcius? With that tool, however, we can describe, explore, discover and predict things in the world around about us in ways and at levels of precision that words or pictures alone could never allow.

That appearance, however, should never let us be discouraged from persevering with mathematics, because by doing so we are unlocking wonderful new ways of understanding our world and solving problems. The following provides some practical tips on ways in which teachers can help provide context for students in mathematics and so seek to more fully engage them in the discipline. Start new topics with a Story or Video, or Visit….

This may be done at the beginning or at the end of a topic.

Arm them with pencils and a clipboard or a tablet and get them to note down anything they see that might relate back to their understanding of the topic. For example:.

Integrate or relate mathematics into other subject areas. Explicitly referencing maths outcomes in planning and programming documents across disciplines is useful if you are using integrated units of work in a primary classroom, but a simple discussion with students about the application of maths during a geography topic or art activity is all it takes. Alternately, brainstorm with your students at the start of a new topic ways in which the mathematics might have applications in other subjects they are studying at school.

Involve local businesses or industry partners in your mathematics program. The equations in this particular task highlight algebraic moves that are useful when students learn to solve quadratic equations by completing the square.
