Q1. Continue this table of $\frac{1}{2}$ for 2 more steps.

• 6 times $\frac{1}{2}$ is $\frac{1}{2} + \frac{1}{2} + \frac{1}{2} + \frac{1}{2} + \frac{1}{2} + \frac{1}{2} = 3$ (or $\frac{6}{2}$).
• 7 times $\frac{1}{2}$ is $\dots = \frac{7}{2}$.

Q2. Can you create a similar table for $\frac{1}{4}$?

• 1 time $\frac{1}{4} = \frac{1}{4}$
• 2 times $\frac{1}{4} = \frac{1}{4} + \frac{1}{4} = \frac{2}{4}$ (Half)
• 3 times $\frac{1}{4} = \frac{3}{4}$
• 4 times $\frac{1}{4} = \frac{4}{4} = 1$ (Whole)

Q4. Draw a picture and write an addition statement: a. 5 times $\frac{1}{4}$ of a roti: $\frac{1}{4} + \frac{1}{4} + \frac{1}{4} + \frac{1}{4} + \frac{1}{4} = \frac{5}{4}$

b. 9 times $\frac{1}{4}$ of a roti: $\frac{9}{4} = 2 \frac{1}{4}$

Q5. Match each fractional unit with the correct picture:

• $\frac{1}{3} \rightarrow$ Circle cut into 3 sectors.
• $\frac{1}{5} \rightarrow$ Circle cut into 5 sectors.
• $\frac{1}{6} \rightarrow$ Circle cut into 6 sectors.
• $\frac{1}{8} \rightarrow$ Circle cut into 8 sectors.
