I have been meaning to try out Manga High, a games-based Mathematics site for a while now – particularly as it is now free to UK schools. Registration is a simple process as is signing up your students. There are many documents available for teachers – see Resources. I received a quick and supportive reply to a query I sent.

I set my very able Year 9s (age 13-14) some challenges on Quadratic Equations as we have been studying them recently and also asked them to explore the resources on the site. I asked for their views, including whether they thought this would help other students. There is no doubt that they were all highly engaged in what they were doing. I wish to explore the quizzes further as these do look promising.

So here are their first thoughts; I’ll update this as more comments come in.

Clara and Emily
We found this website very useful as it was fun yet educational, and we got very competitive playing the quizes which made us want to continue. We think that others will really enjoy this too, particularly year 7s, as it is a fun way to learn. We would like to keep using it!

From Spencer Riley’s TeacherLed the Prime Factor Tree resource provides a very attractive prime factor tree showing the prime factor decomposition for any number from 2 to 99.

Note the choice of Computer or User which means the user can select a number to decompose into prime factors.
By choosing two trees, the highest common factor (referred to as the greatest common factor) and lowest common multiple can be found.
Once both factor trees are complete the prime factors can be dragged to the given Venn diagram and the HCF and LCM checked.

A companion blog to this on Mathematics Starters includes information on Alec McEachran’s Primitives application which provides an excellent visualisation of the prime factorisation of a number.

This WolframAlpha widget gives the prime factor decomposition and divisors of a number. The widget allows you to change the displayed number.

Factorization by Stephen Von Worley

For two stunning vizualisations try Stephen Von Worley’s data visualization on factorization and Jeffrey Ventrella’s Composite Number Tree.
