mathematical fluencies with style and flair, not to mention an afterglow of
insight.”**

The **Mathematical Etudes Project** aims to find creative, imaginative and
thought-provoking ways to help learners of mathematics develop their fluency in
important mathematical procedures.

Procedural fluency involves knowing when and how to apply a procedure and being able to perform it “accurately, efficiently, and flexibly” (NCTM, 2014, p. 1). Fluency in important mathematical procedures is a critical goal within the learning of school mathematics, as security with fundamental procedures offers pupils increased power to explore more complicated mathematics at a conceptual level (Foster, 2013, 2014, 2015; Gardiner, 2014; NCTM, 2014). The new national curriculum for mathematics in England emphasises procedural fluency as the first stated aim (DfE, 2013).

But it is often
assumed that the only way to get good at standard procedures is to drill and practise
them *ad nauseum* using dry, uninspiring exercises.

The **Mathematical Etudes Project** aims to find practical classroom tasks which
embed extensive practice of important mathematical procedures within more
stimulating, rich problem-solving contexts (Foster, 2011, 2013, 2014, 2017a,
2017b). Recent research (Foster, 2017a) suggests that etudes are as good as
exercises in terms of developing procedural fluency – and it seems likely that
they have many other benefits in addition.
