Common misconception
Children may struggle to see that halving is the inverse of doubling.
Only progress to this lesson once children are fluent in doubling numbers zero to five. Present the same visual (e.g. 3 apples + 3 apples) and use this to discuss doubling and halving, revealing and covering one of the two equal parts each time.
