Week 4 - 11/5

Fractions continued...


Hey Skylarks! Happy Monday! :)

This week we are going to be continuing with fractions! We are going to begin by looking at fractions of number before moving onto adding and subtracting fractions!


Don't forget to... Keep smiling! :)

Fractions of amounts!



I hope you are ready for today's fun task! It is all about fractions of amounts! This means you will be using multiple objects to do this, like multi-link. Take a look at the video below and it all becomes a lot clearer!


I would like you to carry out the same task as seen in the video, but you can decide what your objects are going to be. Here are some ideas...

  • Toy cars
  • Lego
  • Marbles
  • Pasta
  • Rice
  • Sweets
  • Grapes... It is up to you! :)


For today we are going to stick with our numerator being 1. I would like you to find the amounts of the following fractions...

  • 1/2 of 10
  • 1/4 of 20
  • 1/5 of 20
  • 1/3 of 15
  • 1/6 of 18


Remember you need to split your objects into EQUAL groups. You can show your answers using objects and using a bar model, just like in the video! :)

Fractions of amounts using the bar model

In this video we look at finding fractions of amounts for both unit and non-unit fractions. We use concrete resources and the bar model to help children 'see...

Changing the numerator!



Hey Skylarks! You did fantastic at yesterdays task and I am super proud of you!


Today I would like you to continue with this task but this time we are going to be changing the numerator! Re-watch the video if needed to remind yourself of what this means.


I would like you to find the following fractions...

  • 2/3 of 15
  • 3/4 of 12
  • 2/5 of 20
  • 5/6 of 24
  • 6/8 of 24


You can display these answers in the same way as yesterday by using a bar model. You can also challenge yourself by explaining each of your answers in sentences. Here is an example below...


2/4 of 12...

The denominator is 4 so I know I need to share 12 equally into 4 groups. I know that 12 divided by 4 equals 3. The numerator is 2, I know this means I need to count 2 of the 4 equal groups. I know that 3 multiplied by 2 equals 6. Therefore 2/4 of 12 equals 6.

Flying through fractions...



Every day you are putting the biggest smile on my face with how well you are doing with this weeks fraction activities! :)


Today we are going to be jumping onto the next step, continuing to use the bar model but making the denominator a larger amount! Watch the video below and all will become much clearer! 


I would like you to find the amount of the following fractions...

  • 3/5 of 25
  • 2/3 of 24
  • 5/6 of 36
  • 4/7 of 35
  • 6/9 of 36

First find the amount of one section of the fraction before then looking at the numerator... exactly as it shows in the video! You could also challenge yourself by explaining each answer just like yesterday. Maybe you could even film yourself explaining? :)

Fractions of amounts using the bar model

In this video we use the bar model and the CPA (Concrete Pictorial Abstract) approach to finding fractions of amounts of unit and non-unit fractions.

Adding Fractions!



So today we are going to move onto adding fractions together. We are going to keep the denominator the same though so the number of parts will NOT change! :)


I would like you to first watch the video below to refresh your memory on these skills before moving onto the sums below. I would like you to draw a diagram to show what is happening when you add each of the fractions together... just like in the video! :)


If you would like to challenge yourself you can also put your excellent explanation skills to the test and explain each of your answers. I have added an example below...


1/4 + 2/4 = 3/4

The denominator is 4, this tells me there are 4 equal parts. In the first fraction the numerator is 1 which represent one of the equal parts. In the second fraction the numerator is 2 which represents two equal parts. Adding these parts together makes 3 equal parts in total. Therefore the answer is 3/4

Adding Fractions (common denominator)

NEW: After watching the film, try this Kahoot! ...

Subtracting Fractions!



Today we are going to use our skills from yesterday, adding fractions, and adding a new skill of subtracting fractions. First of all I would like you to watch the first half of the video below to refresh your marvellous Maths skills! Once you have watched it I would like you to complete the task below.


The task requires you to both add and subtract fractions with the same denominator! :) I am sure you will be amazing at this task and I can't wait to see how you do. Have fun! :)
