Lesson details
Key learning points
- When a whole is divided in half, there are 2 equal parts.
- When a whole is divided into quarters, there are 4 equal parts.
- Two-quarters and one-half are equivalent because they describe the same amount when the wholes are the same size.
Keywords
One-half - 1 of 2 equal parts of a whole.
Two-quarters - 2 of 4 equal parts of a whole.
Equivalent - When two or more things have the same value.
Common misconception
Children may initially think that two quarters is larger than one-half because the numerals in the fraction are larger.
Try to avoid introducing the fractions in numeral form until children are familiar with recognising two-quarters in different representations such as shapes and small sets. Support understanding with stem sentences as modelled in this lesson.
