## Fractions

Year five have been working hard in Mathematics! Take a look at some of the students explaining the different types of fractions in the videos below.

Provide examples of each kind of fraction in a comment below.

## 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.    When do you or your parents use fractions in every day life?

What did you think about the games above?

Compare fractions using the fraction wall above.

## 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 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?

## Area

Year five have been learning about area in Mathematics. Area is the size a surface takes up. Click on the links below to practise your skills.

What else do you know about area?

How do you find the area of a square, rectangle or triangle?

What units of measurement are used?

Jenny Eather’s Maths dictionary may be a great help – click here.

## 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.  Click on the images below to play games to practise your volume and capacity skills.  What objects can you find in your house that hold millilitres and litres?

Convert the following.

6000mL = _____L

5.5L = _______mL

## 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 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. 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.
