New factor challenges in Year 5! The challenge was to manipulate numbers following rules ( as usual!) such as ‘numbers must not be next to a factor of itself’…we could choose factor lines or factor hive…well done to Archie Freya Peggy and Arnold who solved their chosen challenge…the rest of us ran out of time but were well on the way. Archie equalled the published solution for Factor Lines  found by a boy in China- go Archie!
