1. A task setting PowerPoint Pack about adding fractions.

2. LO: To add fractions with the same denominator.

3. As a fraction, how many of the boxes are coloured?
Fractions can be added and subtracted. It is much easier to do when the denominators are both the same number.
Adding Fractions
As a fraction, how many of the boxes are coloured?
First of all we need to know the denominator.
Secondly, we need to find the fractions of the coloured boxes.
Lastly, we add these two fractions together.

4. As a fraction, how many of the boxes are blue?
Adding Fractions
As a fraction, how many of the boxes are blue?
1 of the boxes are blue. 5

5. As a fraction, how many of the boxes are orange?
Adding Fractions
As a fraction, how many of the boxes are orange?
1 of the boxes are blue. 5
2 of the boxes are orange. 5
We now have our 2 fractions!

6. Adding Fractions
To find the amount of coloured boxes, we add both of these fractions together. 2 5 1 5 5 + =
The denominators are both the same number so we
leave them as they are, they don’t get added together (this is very important).
We simply add the two numerators together!

7. Jessie and James share a chocolate bar.
Adding Fractions
Jessie and James share a chocolate bar.
Jessie eats of it. 2 7
James eats of it. 4 7
As a fraction, how much of the chocolate bar did Jessie and James eat all together? 2 7 4 + = 6

8. Adding Fractions
To find the amount of chocolate eaten altogether, we add… 2 7 4 + =
Think: What happens when the denominators are the same?
