Fractions and Decimals

Fraction: Any part of a group, number or whole. When you divide something into equal pieces, each piece is a fraction of the whole thing.

You can use a fraction wall like this to compare fractions with each other.

3D Space

Year five are currently learning about three-dimensional space. 3D shapes have length, breadth and height. Pyramids and prisms take their name from the shape of their base. Prisms have uniform cross-sections (cuts that are parallel to, and the same size and shape, as the base) whereas pyramids have cross-sections that are not uniform

3D Shapes

Take a look at two students explaining the pairs of parallel faces on a 3D object below.

3D shapes are all around us in the built and natural environment! Take a look at the YouTube clip below. 

What 3D shapes can you see at home and/or in the classroom?

Volume and Capacity

Volume can be defined as the amount of space occupied by a 3D object. For example: blocks have volume – they take up space.

Capacity can be defined as the amount a container can hold.

A bottle has volume, it takes up space. It also has capacity, the amount of liquid it can hold.

What objects can you find in your house that hold millilitres and litres?

Convert the following.

6000mL = _____L

5.5L = _______mL

Come up with your own.

Mass

In Mathematics, year five have been learning about mass. Mass measures how much matter is in an object. The metric units for measuring mass include milligram (mg), gram (g), kilogram (kg) and tonne (t). 

Mass

Mass can be written in a number of different ways.

For example: 1600 g / 1 kg 600 g / 1.6 kg   

Take a look at Jenny Eather’s Poster below regarding metric conversions.

Capture

Gross Mass: The total weight – including the contents, packaging etc.

Net Mass: The total weight – not including the packaging etc. (contents only)

Take a look at year five learning about Mass!

What unit would you use when finding the mass of certain objects/animals and items? E.g. whale (t), paperclip (g) and person (kg).  

What are the different types of scales used to measure mass?

Ask your parents when they use mass in their daily lives and where they see g, kg and t.

Multiplication and Division

In Mathematics, year five have been learning about multiplication and division. Take a look at the YouTube clips below to revise long multiplication and short division.

Click here to visit Jenny Eather’s Maths Dictionary. Remember to complete the set activities on Mathletics. 

What do you need to remember when completing long multiplication or short division?

When would we need to use multiplication or division in everyday life?

Find the definitions of the following words and use them in a sentence: product, array, divide, multiply, composite, prime, quotient, remainder, digit and factor.

Time

In Mathematics, the students in Five White are learning about time. Without time we wouldn’t be able to have meetings, meet up with friends or even organise a party!

Take a look at the following time facts.

60 seconds = 1 minute
30 minutes = half an hour
60 minutes = 1 hour
24 hours = 1 day
7 days = 1 week
14 days (2 weeks) = 1 fortnight
28-31 days = 1 month
12 months = 1 year
365 days = 1 year
366 days = 1 leap year
10 years = 1 decade
Every four years = a leap year
100 years = 1 century

Can you think of examples of when the above time facts are important?

For example: we need to know when a year has passed to know how old we are!

Addition and Subtraction

The next topic in Mathematics that we will be learning about is addition and subtraction. We use addition and subtraction in our everyday lives more than you probably realise! Your parents might use addition and subtraction as they calculate how much their groceries are going to cost when they are at the supermarket, Miss Azzopardi uses addition and subtraction  when marking students’ tests and you might use addition and subtraction when you purchase items from the canteen to see if you have enough money to buy the items you want or to work out your change.

Can you think of any other times people might use addition and subtraction? Leave a comment with your answers!

Challenge: Ask your parents to write a comment about the times they use addition and subtraction in their daily lives. They might use it at work or around the house!

Try the following games to improve your addition and subtraction skills. Leave a comment below explaining which game(s) you played and what you thought of the game(s).

The Days in Each Month

It is important to know how many days there are in each month. The following rhyme will help you to remember.

30 days have September,
April, June and November
All the rest have 31
Except for February’s 28
Except in a leap year when February’s days are 29. 

Watch the YouTube clip below.

Can you find any other rhymes/videos to help you learn the number of days in each month?

When would you need to know how many days there are in a month?
