Common misconception
Children may fail to appreciate the importance of the equals sign in an equation, e.g. making errors such as 16 = 4 + 20, or confuse the value of the digits, making errors such as 43 = 4 + 30
Use the language of parts and whole to activate/link to prior learning. Encourage drawing of own part-part-whole models. Encourage children to spot errors and explain why they are are incorrect and to articulate their thinking around correct answers.
