Lesson details
Key learning points
- If two parts are the same size, but a different fraction of the whole, the whole with the most parts will be greater.
- If two parts are different, but are the same fraction of the whole, the whole with the larger part will be greater.
- If the size of the part and the fraction of the whole are different, we need to calculate to determine which is greater.
Common misconception
Children may confuse the different methods used to compare fractions of amounts and their wholes.
Guide through questioning. What is the same/different? Can you represent this visually? What is the size/value of the parts? What fraction of the whole is each part?
Keywords
