A great vizualisation or diagram can make a very good starter…

Mathematics, Learning and Technology

I have several references in various places on this blog to some great visualizations.

Time to put them all together!

Jeffrey Ventrella’s Composite Number Tree

From Jeffrey Ventrella this wonderful **Composite Number Tree** – I have used this successfully with many students. It makes a great starter. Students can work out themselves how the tree is being formed and comment on any patterns they notice.

Another **excellent visualization**, animated factorization diagrams comes from **Data Pointed**. And here is Stephen Von Worley’s blog post, **Dance, Factors, Dance **which tells the tale of the animation. Noting his reference to Brent Yorgey’s factorization diagrams led me to Brent’s own later post, **More factorisation Diagrams**. I love Brent’s use of colour here. If you want even more on these great diagrams he has more information and links on **this page** on his blog, **The Math Less Traveled**
