Lesson Details

Key learning points

If mixed numbers have the same whole number parts, then the size of the fractional parts determines the greater number.
When we compare fractions that have the same denominator, the greater the numerator, the greater the fraction.
Knowledge of comparing proper fractions can help when comparing mixed numbers.

Common misconception

Children may compare the fractional part of the mixed number first rather than the more significant whole number part.

What do you notice? If the whole number is the same, we need to look at the fractional part. If the denominators are the same, we need to compare the numerators - the smaller the numerator the smaller the fraction.
