The clarity of the argument, and the detail in the mathematics, make this a real piece of "mathematics in context". However, while this might be not described as "mathematics for the faint hearted", there are classroom implications for application, interest, and motivation. "All things solar" have seen a rise in popularity through the serious…

In this article, the author discusses the findings of a micro research project which explores students' perceptions of learning mathematics when embarking on undergraduate studies in education. The theme for this study is the consideration of a possible link between adults' perceptions of learning mathematics and the effect this may have on their…

Multiplication facts are difficult to teach. Therefore many researchers have put a great deal of effort into finding multiplication strategies. Sherin and Fuson (2005) provided a good survey paper on the multiplication strategies research area. Kolpas (2002), Rendtorff (1908), Dabell (2001), Musser (1966) and Markarian (2009) proposed the finger…

In this article, the author suggests a cross-curricular idea that can link with PE, dance, music and history. Teacher David Schmitz, a maths teacher in Illinois who was also a square dance caller, had developed a maths course that used the standard square dance syllabus to teach mathematical principles. He presents an intensive, two-week course…

One sign of a good task is that it will work just as well with Year 7 as with Year 13. The author asks learners to use graph-drawing software to draw a picture with graphs. He uses his imagination to suggest what a particular curve might resemble and helps learners to adjust their drawings to achieve what they are trying to make. Sometimes, one…

This article reports on the findings of a research project whose aim was to support and enhance the teaching of risk at Key Stage 4. An innovative and cross-curricular approach has been used, based on modelling socio-scientific issues using new technological tools, designed specifically to enable the consideration of ethical and social issues,…

Contextual mathematics is an area of mathematics teaching and learning through which researchers and educators believe that mathematics is better taught, and learned, if connected to real-life situations and problems. It is also very helpful if it makes sense in the students' world. Thus, the author decided to start a project by creating a blog,…

A formal approach to the differentiation of vectors from an axiomatic point of view is introduced, and applications to dynamics are presented. (DT)

Notation and definition of the derivative function are discussed. (DT)

Twelve problems which can be proved by the "mailbox principle" are stated and discussed. (DT)

The characteristic shape of the normal distribution, one hump and two tails, is discussed. The reasoning is based on variation, combinations, probability, and logarithms. The purpose is to be able to answer some of the "whys" students might ask. (LS)
