Monday: In today's lesson the focus will be on ordering decimals, to get you warmed up why not click on the link below and have a go at the balloon pop game.

Ordering Decimals Balloon Game

Once you've got your Maths brain into gear with those decimal numbers have a watch of the Corbett Maths video below that shows you how to order decimals if they either all have the same amount after the decimal point or if they have different values after the decimal. Once you have watched this have a go at the worksheet below the video.

## Ordering Decimals - Primary.mp4 Tuesday: There are 2 parts to today's lesson - the first part focuses on finding missing angles from a straight line and the second part looks at how you will find a missing angle from around a point.

First, let's recap on the different types of angles that you might come across. Now that you've reminded yourself of the angle names take a look at the video that explains how to find missing angles from a straight line - remember, a straight line is 180so once you have found the missing angles your answer should total 180.

## Angles on a straight line.mp4 Now you've watched the video and had a little bit of practice it's time to give it a go on the worksheet attached below.

Well done for having a go at that - now it's time to move on to finding missing angles around a point. This time you need to remember that angles around a point add up to 360o. Take a look at the video below and then have a go at the worksheet underneath the video.

## Angles around a point.mp4 Wednesday: Today’s lesson focuses on plotting coordinates to make shapes. Remember when you plot coordinates you read along the x – axis (the horizontal line) and then up/down the y-axis (the vertical line). When you are completing a shape you will need to take into account what points you already have plotted and use the x and y-axis points that are there.

Take a look at the video below and see how the missing coordinates are plotted to complete the shape – sometimes you will see that you are presented with some points and then need to add the final point to make the shape, other times you will be able to count the squares on the grid to help you find where the missing point goes and then you can identify the coordinates. Once you have watched the video have a go at the worksheets attached below.

## Coordinates and shapes.mp4 Thursday: Today you are going to focus on converting between fractions, decimals and percentages. This is where you will need the following information:

• Per cent means out of 100
• Your decimal place value – tenths, hundredths, thousandths

If you are converting from a percentage to a fraction eg: 40% as a fraction would be 40/100 (it’s 40 out of 100) and if you made this into a decimal it would be 0.40 the last digit of the number is in the hundredth column.

Another example: 56% would be 56/100 which would be 0.56 as a decimal

If you were given the decimal first you can use your place value knowledge to help you: 0.72 is the same as 72/100 as it is 72 hundredths which is the same as 72%.

Watch the video below for more explanation and to have a go at some of the examples you are presented with – once you have watched the video have a go at the worksheet below.

## Converting Between Fractions, Decimals, and Percentages.mp4 Friday: Today you are going to work more on converting between fractions, decimals and percentages to make sure you have converted between the different amounts.

Converting Decimals to Fractions

When you convert decimals to fractions you will need to use your place value knowledge and look at what column the last digit is in. For example, if the number is 0.3 then the number finishes in the tenths column, this would then mean that your denominator is 10 and the 3 would be your numerator = 3/10

If your number was 0.47, this finishes in the hundredths column so your denominator would be 100 and the numerator 47 = 47/100

And the same would then apply if your number was 0.743, this finishes in the thousandths column so the denominator would be 1000 and your numerator 743 = 743/1000

Converting Percentages to Decimals

When you convert from percentages to decimals you need to think about the fact that per cent means out of a hundred and your place value knowledge of hundredths.

If you were converting 86% to a decimal you would convert it to 0.86 – the 6 of the 86 ends in the hundredths column whereas if you were converting 4% to a decimal you would convert it to 0.04 as it is 4/100, the number must end in the hundredths column.
