Composite Number Tree

Jeffrey Ventrella’s Composite Number Tree

Twitter can be so useful – I usually check the #mathchat tweets and saw Richard Wade’s tweet with a link to a Teach Maths newsletter, on ‘Ten Great Ideas’. The first item includes this wonderful Composite Number Tree by Jeffrey Ventrella – this make a great starter. Students can work out themselves how the tree is being formed and comment on any patterns they notice. Also included in the first Newsletter item is the excellent Primitives application by Alec McEachran, I included this myself in an earlier post.
