Similar Triangles Mathematical Art

I have been following along with Annie Perkins ' twitter #MathArtChallenge . She has been posting a starting point each day and whenever I have had time I've joined in. Here is the initial prompt for the similar triangles activity: The #mathartchallenge today is from @shskaercher : similar right triangle patterns. See below for a link to a fabulous video he made explaining. pic.twitter.com/RP1HV4tJJa — Annie Perkins (@anniek_p) April 19, 2020 I had a moment and some coloured paper so I joined in. My explorations can be seen in this twitter thread . I wanted to take a moment to reflect on the process I went through while working on this project. I started out with Annie's examples in my mind. I liked the spiral she had created and I wanted to examine it closely. Why does it spiral? Which sides match? How quickly does it shrink and so on. Once I had the pieces in my hands however I realised there was so many possibilities to explore. I did explore a whole

Random Pentagon Generator

So, I made a Random Pentagon Generator: Here are some examples of random pentagons: I guess the first question you might ask is "Why?" The task this week for the #beingmathematical twitter chat was to explore the pentagons that can be made on a 9-pin geoboard. Diary Date! #beingmathematical is back again and starts this Thursday 2nd May 8pm-9pm BST. This week it will be hosted by @MichaelOllerton and @helenjwc Who’s joining us? Here is this week’s task: Explore the pentagons that can be made on a 9-pin geoboard. Here is one example: pic.twitter.com/fuEwzrxwle — Teachers of Maths (@ATMMathematics) 28 April 2019 I had a play before the chat started. If you haven't seen this task before I recommend you have a play yourself before reading further! First I doodled a bunch of different pentagons that all used the top corners as vertices: Some initial explorations I felt a bit overwhelmed at the number of different pentagons I was finding

Maths Club Ideas - Printables

This is a follow up to my post about maths club activities requiring only paper and scissors . If you have access to a printer you might like to use these activities that only need a teensy bit of prep. I like using dotty circles, templates can be found half way down this page, there are some great activities you can explore. My favourite activity is investigating different ways of drawing stars , it has really great links to factors and multiples. Then you can look into some angles activities, triangles in circles or even angles in the stars themselves. Dotty paper is great for creative maths projects, it comes in isometric and squared versions and is very versatile. Isometric drawing is great fun, print some paper here and have a go. I would recommend starting by drawing some simple shapes, this activity with four cubes might be a nice place to start, then you could look at other 3D shapes and how to draw letters. Tessellations are another activity that can be
