Common misconception
Lots of children will want to make use of a written method such as column addition straight away without considering the use of mental methods with jottings.
Encourage the children out of their comfort zone by praising efforts and allowing them to feel motivated by any small successes in the method. Explain to them that this understanding will help them to be better mathematicians in the long run!
