# Mathematics 2.1

## Week Six

Each day this week you have an arithmetic warm-up and your core learning.

We are all learning how to calculate percentages in the arithmetic warm-up.

Please complete the arithmetic warm-up prior to your core learning each day.

This week we are learning how to estimate, calculate, measure and draw angles in Year Five

In Year Six, we are learning to calculate area and volume.

## Monday 8th February

### Learning for Year Five Yellow & Green Group

Identify the types of angle:

• ACUTE - less than 90°
• OBTUSE - larger than 90° but less than 180°
• REFLEX - larger than 180°

CHALLENGE

1. Choose one triangle and one quadrilateral.
2. Measure the angles in each.
3. Add the angles.
4. Write the sum of the angles of your chosen shape inside the shape.

The sum of the angles of a triangle = 180°

### Learning for Year Five Green and Yellow Group

Open the document below and follow the instructions for today's learning.

Watch Monday's lesson again if you are unsure how to count the area.

cm squared paper is available below in case you do not have this at home.

## Introducing Volume.

Building layers on the base of a 3D shape to demonstrate width x length x height = volume

### Learning for Year Five Green and Yellow Group

After watching the short video we can infer that if you know the number of cubes on the base of a cuboid, you can multiply the base by the numbers of layers to find the volume.

For example,

A cuboid with a width of 2 cubes and a length of 4 cubes would have 8 cubes on the base layer.

If this cuboid had 6 layers of cubes, the height would be 6 cubes.

It is now easy to use the formula width x length x height to calculate the volume.

width = 2

length = 4

height = 6

2 x 4 x 6 = 48cubes

Use this formula to calculate the volume of each shape in the worksheet below.

TOP TIP

Remember - you can multiply the numbers in any order because

2 x 4 x 6 = 2 x 6 x 4 = 4 x 2 x 6 and so on.

Sometimes changing the order you multiply can make the calculation easier because you can use known facts to help you.

Here is an example 20 x 7 x 35 =

I would calculate 20 x 35 first because I know how to multiply by 20 (double the number and multiply by 10)

20 x 35 (double 35 is 70, and 10 x 70 is 700) = 700

Now it is easy to multiply by 7 because I know that 7 x 7 = 49

700 x 7 = 4,900

### Learning for Year Six Red Group

squared paper (a sheet is available below Tuesday's learning)

a pair of scissors

Follow the instructions in the link below and send your answers to for some feedback.

### Learning for Year Six Red and Blue Group

Today I would like you to choose your challenge.

Below are three sets of ratio and proportion problems.

The sets become increasingly challenging.

## Week Two

This week we are learning about measures in year 5 and negative numbers, and calculating the mean in year 6.

## Tuesday 12th January

### Learning for Year 5 Yellow and Green Group

Find Three Items

For this activity I would like to find three small items that you can measure the length of in mm

Write the items and the length in mm and then convert each length to cm.

Now find three items that you can measure the length of in cm.

Write the items and the length in cm and then convert each length to mm and to m.

Now find three items that you can measure the length of in m.

Write the items and the length in cm and then convert each length to mm and to cm.

Remember:

• to convert from cm to mm you must  multiply by 10 because 10mm = 1cm
• to convert from mm to cm you must divide by 10 because 10mm = 1cm
• to convert from m to cm you must mulitliply by 100 because 100cm = 1m
• to convert from cm to m you must divide by 100 because 100cm = 1m
• to convert from m to mm you must multiply by 1000 because 1000mm = 1m
• to convert from mm to m you must divide by 1000 because 1000mm = 1m

## Capacity Problem

### Learning for Year 5 Yellow and Green Groups

Your task today is calculate how many 5ml teaspoonsful of water would you need to fill:

1. A mug with 175ml capacity
2. A kettle with 1.7l capacity
3. A wheelbarrow with 200l capacity.

Remember to convert the capacity of the kettle and wheelbarrow from litres to ml.

## Converting Units of Measure

### Learning for Year 5 Green and Yellow Group

You will need:

• decimal sheet
• two sets of numbers cards 0-9

(see resources below)

• a dice

Instructions:

1. Choose three numbers cards and place them on the decimal sheet.  For example, if you chose 3, 4, 7, you might make 3.74
2. Roll the dice
3. Use the table to create a calculation.  For example, if you roll a 4 the calulation would be: 3.74 x 10
4. Write this calculation and the answer 3.74 x 10 = 37.4
5. Repeat until you have ten calculations.
 roll operation 1 ÷ 10 2 ÷ 100 3 ÷ 1000 4 x 10 5 x 100 6 x 1000
