Show transcript
Fluent calculation requires flexibility to move between mental and written methods and supports us to be efficient.
Looking at the numbers within a calculation supports us to know whether to use a mental strategy or written method.
Mental strategies work best when known facts are used.
Written methods work best when the numbers given are precise or when exchanging is involved.
