Today, we are going to continue to add fractions.
Have a look at the in focus question below.
We need to add the total amount of pizza that was eaten by Elliot but how can we add these fractions knowing the denominators are not the same?
Think back to the lesson from yesterday, we know that they need to be the same.
How can we make 1/3 and 1/6 the same?
We know that 3 x 2 = 6 so 1/3 is equivalent to 2/6 as shown by the diagram above.
Next, if we add together 2/6 and 1/6 we get a total of 3/6.
This is equivalent to ½.
Elliot ate half a pizza in total.
Now, have a look at Q2 above. We are going to find the sum of the 3 fractions.
What does Sum mean? That’s right. We are adding them together.
How can we make them the same?
Well done, they can all be converted to sixths.
Can you convert them and see what fractions you make.
Make sure you write the fraction out with the arrows and think about how to make the denominator a 6. What multiples do you need to use and don't forget to multiply the numerator too.
Well done if you got 1/6, 3/6 and 2/6.
The total would be … 6/6 = 1 whole one.
Now have a go at the guided practice section above.
Below is worksheet 9. You will be sent this on Seesaw to complete.
Remember to make the denominators the same first. Think of your times tables to help you.
