To finish our learning about sequences, I introduced my students to the Fibonacci sequence and we had a go at drawing Fibonacci Spirals. The attached ppt includes a link to Vi Hart’s video, a small activity, some art work, and instructions to draw the spiral (although I didn’t actually use the instructions, instead just used the visualiser and worked through with the students).

When preparing a resource to take and share at mathsconf4, I wanted to share something which I find valuable and seems to make a difference to pupils learning. So I chose a resource, originally from TES (complex_number) for a topic I find pupils struggle with, yet is a basis for so much mathematics: converting between fractions, decimals and percentages. The resources I use are for groups with little or no understanding of the connections between the three as they start off quite basic.
It starts with a slideshow of artwork where proportions could be viewed as a theme. This includes works from Piet Mondrian, Victor Vasarely, Ellsworth Kelly and Frank Stella. With a quick review of what fraction, percentage and decimal (based on a 100 square, so using £s and p to support the decimals) mean, pupils then create their own artwork on their 100 square. They then use their art work to write the fraction, percentage and decimal of each colour used. The advantage of using this resource has been to consolidate the connection between the fraction out of 100 to the percentage. The next step is to move onto a 50 grid, 25 grid, 20 grid and 10 grid, and hence the need to change the fraction to out of 100 in order to write the percentage. Accompanying the grids are some fraction, percentage and decimal tables, with an extra column for the fraction out of 100, for pupils to practise their conversions. A similar resource I’ve used is a skittle pie charts. I’ve done this by giving out skittles (20, 25 or 40) and pupils to make their own circles, grouping the colours, section ing them off and writing the fraction, percentage and decimal for each section. I’ve also given out a template for pupils to colour in given skittles (this was actually to help with interpreting pie charts, but linked in nicely to the fractions, percentages and decimals work the pupils had completed previously.
