Addition of fractions with renaming

In pairs:

Add $\frac{1}{2}$ to $\frac{1}{4} .$

Use the fraction board to write the equivalent fraction of $\frac{1}{2}$ in terms of quarters.
$\frac{1}{2} = \frac{}{}$
Add the equivalent fraction of $\frac{1}{2}$ to $\frac{1}{4} .$
$\frac{1}{4} + \frac{}{} = \frac{}{}$
Discuss in your group and share with other groups.

Work out: $\frac{1}{3} + \frac{3}{6}$

$\frac{1}{3} + \frac{3}{6} = \frac{2}{6} + \frac{3}{6} = \frac{5}{6}$

$\frac{1}{3} = \frac{2}{6}$

$\frac{1}{4} + \frac{1}{2} = \frac{1}{4} + \frac{}{4} = \frac{}{4}$

$\frac{2}{3} + \frac{1}{6} = \frac{}{6} + \frac{1}{6} = \frac{}{6}$

$\frac{5}{8} + \frac{1}{4} = \frac{5}{8} + \frac{}{8} = \frac{}{8}$

$\frac{1}{2} + \frac{1}{6} = \frac{}{6} + \frac{1}{6} = \frac{}{6}$

$\frac{2}{5} + \frac{1}{10} = \frac{}{10} + \frac{1}{10} = \frac{}{10}$

$\frac{3}{4} + \frac{1}{12} = \frac{}{12} + \frac{1}{12} = \frac{}{12}$

$\frac{4}{9} + \frac{1}{3} = \frac{}{}$

$\frac{1}{2} + \frac{3}{10} = \frac{}{}$

$\frac{1}{6} + \frac{7}{12} = \frac{}{}$

Gakii spent $\frac{1}{8}$ of her pocket money to buy a rubber. She used $\frac{1}{4}$ of the pocket money to buy a handkerchief.

$\frac{1}{8}$ $\frac{1}{4}$ = $\frac{}{}$ $\frac{}{}$ = $\frac{}{}$

Joshua bought $\frac{1}{2}$ kg of millet flour from a shop. Caleb bought $\frac{1}{4}$ kg of the millet flour from the same shop.

$\frac{1}{2}$ $\frac{1}{4}$ = $\frac{}{}$ $\frac{}{}$ = $\frac{}{}$ (kg)

Amina used $\frac{1}{3}$ of the water in a tank to wash clothes. She used $\frac{5}{12}$ of the water for cooking.

$\frac{1}{3}$ $\frac{5}{12}$ = $\frac{}{}$ $\frac{}{}$ = $\frac{}{}$ = $\frac{}{4}$
