Now that children are familiar with like fractions, they are ready to work with unlike fractions. This fun and interactive game, doubling up as an interactive worksheet, introduces Grade 5 children to adding fractions with different denominators using their prior knowledge of equivalent fractions.

What’s inside?

- Form a visual understanding of adding fractions with unlike denominators with the help of fraction bars.

- Utilize the number line to estimate the sum by rounding off the fractions to either 0, 1, or 1/2.

- Gradually move on to addition sentences, filling in the missing numbers in the steps.

- Consolidate the understanding without relying on visual models.

Real-World Application - Buying Flour

When preparing cupcakes and waffles on a Sunday morning, we need, say, 1/2 cup of flour for cupcakes and ¾ cups of flour for waffles. To buy enough flour for both, we would add the two fractions with unlike denominators (in this case, 1/2 and 3/4).

What’s next?

Children can now begin to carry out subtraction of fractions with unlike denominators and also learn to operate on mixed fractions.
