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.”
