“If your child sees 3/5 and 3/8, can they tell you which is bigger just by thinking about the size of each piece — without needing to draw it out?”
Full guide and materials
- Activity. Compare two fractions with the same numerator or the same denominator by reasoning about size; record comparisons with >, =, or < symbols
What to notice. Compare 3/8 and 3/4: same numerator, larger denominator means smaller pieces so 3/8 < 3/4 • Compare 5/6 and 2/6: same denominator so 5/6 > 2/6 • Justify a comparison using a visual model and explain why both fractions must refer to the same whole
