Week Two

Monday 28th September,

Today we are going to be looking at rounding. Rounding involves understanding the Place Value of numbers. We have looked at rounding before in Year 3 and now it's time to revisit it again.

Rule:

Numbers ending in 1, 2, 3, 4 bring it down, 5,6,7,8 raise it up.

Good Luck

Week Two

Tuesday 29th September

Today we are looking at the Place Value of numbers, so you may like to revisit the Place Value Grid we have looked at. I have attached a blank copy for you to.

The lesson is slightly different today and comes down to thinking outside the box. You will need to play around with the numbers, which is why I suggested to use the PV Grid. You may also find that some questions may have more than one answer, so challenge yourself to find more than one possibility.

Finally you will see some adding and subtracting. I know in class we have started re looking over the column method if you are comfortable with this please use it otherwise you could use a blank numberline.

I have attached a video about subtraction to support you

Column Method Subtraction with Regrouping - https://www.youtube.com/watch?v=yxwa_GXoXSU

When using the numberline, put one number either end and then using your knowledge of place value, round up to the nearest 10 then count on in 100's, 1000's and then finally add all your jumps up together at the end.

Enjoy :)

Week Two

Wednesday 30th September

Challenge Day!

Today I want you to apply all the learning over the last week and have a go at the challenge. You have 20 numbers you can use and you can only use them once to complete the statement.

You will need to think about what the question is telling you and process where the numbers fit best.

If you finish you may like to make a similar question yourself for someone else to answer, Me if you wish!

Send them to me on Class Dojo and I can post them or try to solve them.

Good Luck

Hello Year 4,

I hope you are all keeping safe and well at home during this difficult time. Thank-you again parents for your continued support with your child's education.

Attached for Monday and Tuesday is some work for you to be getting on with. I had planned a bit of a recap as it was areas we were not yet fully secure on and I wanted us to think and delve deeper.

Monday Lesson:

With the number-lines activity I want you to think about placing numbers accurately on it, like we did it class. Thinking about what the number-line tells you! For example if the number-line is between 8,000 and 9,000 and a mark is shown a 1/3 of the way up we would be looking at a number around 8,300. It may also ask you to have a go at finding out what each interval is. Remember we talked about adding all the intervals up, finding the difference between the two numbers each end and dividing it.

Tuesday Lesson:

It's a recap of Roman Numerals, which we were having lots of fun exploring. I have attached three challenges. Please feel free to have a go at what you can. Remember to work out the numeral by following the rules:

The roman digits I, X and C are repeated up to three times in succession to form the numbers.

When a digit of lower value is written to the left or before a digit of higher value, then the value of the lower digit is subtracted from the value of the digit of higher value.

Roman Numerals:

1 = I    5 = V     10 = X     L = 50      C = 100     D = 500      M = 1000

The activity looks at adding numbers and subtracting. Think back to Year 3 and how we solved addition and subtraction problems. Convert the numerals to numbers before doing this and then convert back to numerals.

For example :

XI + ____ = XX

11 + ____ = 20

20 - 11 = 9

9 = IX

## Worksheets

Wednesday Lesson.

Hope you have all been getting on well at home with your learning. Thank-you to those who emailed the school office with the work you have been doing.

If you would like to email me, my email was sent out on the Back to School Powerpoint sent out at the beginning of the year and I will do my best to get back to you as quickly as I can.

Today we are looking at partitioning four digit numbers. This is something we have done in both Year 3 and Four. I have included images to help you and for you to work with, just like we have in class. You may choose to draw these if you wish.

You will need to look at the image displayed and work out the number that is shown, for example 2345.

I then want you to complete the sums of how this number can be partitioned.

2000 + 300 + 40 + 5.

It can also be made as

1000 + 1300 + 40 + 5 - I have  exchanged a thousand and joined it onto the 300.

2000 + 200 + 140 + 5 - I have exchanged a 100 and joined it to the 40.

This will help you understand how to make numbers in different ways.

Have a go and see how you get on :)

Thursday Lesson

Thank-you again to those children/ parents who have sent in work to show us what you have been up to. It is great to see you consolidating on the learning we have done in school.

Today's task is looking at comparing numbers, we did this with 100 numbers back in Year 3 so now we are looking at thousand numbers.

Symbols: < > =

Vocabulary: Less Than, Greater Than, More Than, Equal to

You will see on the worksheet uploaded that there are some visuals to help you; the place value grid and counters, this image will help you in working out the other questions, but also you may wish to use the Base 10.

Have a go at drawing out the numbers so that you can visually compare. When comparing we start on the left and work across. Compare each number and refer to a number-line if you need to.

Good Luck

Friday Lesson,

It's the end of the week and well done for being so fabulous with your home learning at home.

Today is a continuation of yesterday's lesson but looking at the work more abstractly. You may wish to use Base 10, Place Value Grid or PV Counters to help support you in working out the answers.

Some questions will require you to explain to me what you believe is right or not through the use of images, so think back to class and how we do this - it may be easier for you to explain to an adult before writing it down.

Thanks Miss Wood
