Whissendine and St Nicholas Primary School

Thursday 17th January

Parents workshop-Understanding progression in calculation in

order to support your child at home.

“Development of memorisation, accuracy and fluency is important. However, this must take place in parallel with development of

understanding and reasoning because:

• Children who do not understand what they are doing often make errors when choosing and carrying out procedures, cannot

reconstruct steps, cannot self-monitor their work, and cannot check for reasonableness

• Life in a global changing economy requires adaptability; it is difficult to be adaptable if you do not understand what you are

doing.”
