Continuing my theme from last week I have added a new page to the Investigations series – one of my all time favourites – Happy Numbers.
I have also added further resources to the Investigations – Links and Resources page. From the National STEM Centre which is an incredible source of resources for STEM subjects we have
Lorraine Mottershead’s book: Investigations a complete book by including solutions to the puzzles and investigations.
Also on the NMoational STEM Centre from David Kirby and Peter Patilla we have Maths Investigations – Pupils’ Workshop together with a comprehensive teachers’ guide.
There are 20 happy numbers in the first 100 natural numbers. Out of those, there are three perfect square happy numbers: 1, 49 & 100. You can read more about happy numbers here: http://www.glennwestmore.com.au/happy-numbers/
