5.3.21 Roman numerals

As a part of our time in Year 3 we look at the number system that the Romans used. You will need to look at the Powerpoint first. 

4.3.21 halving (odd Ones)

As with yesterday we are halving odd digits, but this tome we are doing it with our Ones digits.
As we know a half of one is ½ when we write it as a fraction, I just thought I'd remind you as you will need that information.
Watch the (short) video first and that will help πŸ‘

3.3.21 Halving (odd number of tens)

If you watch the video first it will help you to do this. We are looking at halving numbers of tens such as 30, 50 and 70. 
After that you can use your answers from the first sheet tp help you answer the next sheet.

2.3.21 Estimation (adding)

Ok, today you are going to use your rounding skills to estimate the answer to some addition calculations. After that I would like you to choose four of the calculations to work out the exact answer. Make sure you watch the video first as that'll help πŸ‘ PS: don't forget the challenge!

26.2.21 solving word problems

I have made a short video on how to use your expanded addition, and bar model, skills to solve word problems. If you watch that first it will help.
The worksheet looks a bit strange because I couldn't find any appropriate questions elsewhere, so I took some photographs from our Maths text books. if you work through them and follow the method they should be a bit of a challenge, but nothing too dreadful.

Expanded column addition (the next stage!)

You were all fantastic at the column addition  method we used before half term, now we need to move on to the next step. 
You will all be amazing at this πŸ‘

24.2.21 Bar Model Subtraction

Now, we have seen bar models before - they are really good way to visualise a problem.
Make sure you watch the video first, and that will help.

23.2.21 Subtracting a 2 digit number from a 3 digit number

We've already used a numberline to find the difference between 2 numbers, this is just the next step. It's a tiny bit harder, but not much and you can all do it!

Expanded column addition part 2

You all did such a fantastic job of expanded addition part1 it's time for us to try the next stage.

I know you'll be great at this πŸ’ͺ

Make sure that you watch the video first, then have a go at the sheet - don't forget the challenge.

10.2.21 Expanded column addition (don't worry it isn't as complicated as it sounds)

Today I'm going to show you how we do column addition in Year 3 (its the beginnings of a different way to add numbers). Please make sure you watch the video first, it is important that you follow the method correctly. You need to partition the numbers, make sure you set the work out correctly and then add the numbers - but watch out! You need to look out for numbers that need carrying (this will make sense after you have watched the video).

Subtraction (choose which method to use 🧐)

Here are some subtraction calculations for you to solve. You now know different ways to do this, you can use the triple jump, near multiples or subtract using your Tens & Ones. If you're thinking
"what on Earth is Mr Henry talking about," I have made one of my astounding (πŸ€¨πŸ˜‚) videos to remind you. Don't forget to do The Pit.

5.2.21 Subtracting near multiples

Ok. 
Here we go.
This is one of those Maths skills that can be a bit mind-blowing at first for some of us (it was for me when I learnt about itπŸ˜‚). Having said that I am sure you will all be great at it, we have looked at it before but it was a while ago. Anyway, watch the video I've made , that will help. Well I hope it will 🀞. 
There are 3 sections or you to do. Try to complete at least 2 sections and don't forget to have a go at The Pit.

3.2.21Function Machines (Don't panic πŸ‘)

Today's work builds on what you did yesterday, and some of your times table work. 
It will help if you watch the video first, hopefully.
Have fun, they aren't as difficult as they look 🧐

2.2.21 multiplying and dividing by 10 and 100.

Please watch the clip I have posted (I hope that you can access it 🀞), that will help you to understand how to solve these problems.
Also, please try to do the challenge, these are important - they are like exercises for you brain

1.2.21 Multiplying and Dividing by 10

29.1.21 Reading (slightly more difficult) bar charts

​​​​​​​Today you have another bar chart to read, be careful with this one because some of the bars don't reach a full 100m. 
Question 8 involves converting metres to kilometres, we haven't done this yet so feel free to ignore this question. If you want to do it this might help:
1000m = 1km
so to convert from m to km divide by 1000 for example
1200m = 1.2km
3400m = 3.4km  

28.1.21 Reading bar chart

Today you have a bar chart reading task. There is no video for this, but I will explain on our Zoom meeting. We have definitely had a small look bar charts in Year 3, so I think you'll do a great jobπŸ‘)
(Read questions 9 and 10 carefully!). 
Have a go at The Pit as well - it is one of those challenges that you need to try different combinations in, until you get the correct one. Put some numbers in, if they don't work try some others.
 

27.1.21 Reading pictograms

Ok, yesterday you were making pictograms today it is time to try and read (adults use the word interpret) some pictograms. 
Today you have a choice of tasks:
- the usual, Whiterose, sheet
or
- something more challenging.
It is probably still a good idea to watch the video first.
The Pit is still there for you to try πŸ‘  

Spr3.6.1 - Interpret pictograms

26.1.21 Drawing pictograms

Pictograms are a good way of displaying data. These activities will remind you how to draw them.

Spr3.5.5 - Draw pictograms

22.1.21 Venn Diagrams

Venn Diagrams are another way to sort data (another word for information). Have a look at the PowerPoint and then try sorting the 3 digit numbers.
If you can't print the sheet off you can write your answers on some paper. You could even find a cylinder (maybe you have a jar you could use) and use that to make your own Venn Diagram πŸ‘

21.1.21 Carroll Diagrams

Today we are going to start looking at data handling (you've all done a great job with the money work).

These are Carroll diagrams and they are a way that you can sort information/data.

Have a look at the PowerPoint first, it is about sorting shapes but it will help, and have a go πŸ‘

20.1.21 Giving change.

Today we are going to look at calculating change. This time it is change from more than £1. 
The best way for us to do that is to use the skills we used yesterday (your bonds to 100 skills)
Example:
You spend £2.83 from £5.00 this is 
£5.00 - £2.83.
First you need to get to the new whole £ 
using number bonds this is 17p. 
This takes us to £3, now we need to get to £5 
we add £2.00
£2.00 + 17 = £2.17 change

Give change

19.1.32

Today I want you to practise giving change for £1. This involves using your Number bonds to 100.
Can you remember what we say to ourselves when we are doing this? πŸ€”
Yes, that's correct,  we say, "make 9 make 10." 
For 36 there is a 3 in the T column and a 6 in the O. This means we need  to add 6 Tens and 4 Ones = 64
So the number bond to 100 for 72 would be 28.
For part 2, don't forget to add the two items together before you find the change.

Friday 15th January 2021

Today you are going to practise adding money, which can become quite complicated. I find that the best way to do it is to add the pounds together, and convert your answers to pounds and pence. 
£3.23 + £2.38 =  
£3.00 + £2.00 = £5.00
23p + 38p = 61p
£5.00 + 61p = £5.61
Good luck & have fun!

Spr3.4.5 - Add money

Thursday 14.1.21

Today's maths is converting pounds and pence. As I said in our zoom there are 100p in £1 (but you know that already don't you!), so 345p = £3.45. For some reason on this sheet they would write it as £3 and 45p, 

but that isn't really the correct way to do it. If you watch the video first it'll help you.

Spr3.4.4 - Convert pounds and pence

13.1.21

Today's work combines the work you have done so far. 
When you are looking at question 6 read it carefully and remember that the silver coins are 5p,10,20p and 50p

Spr3.4.3 - Pounds and pence

12.1.21

Today, to build on yesterday's work, here is some work to review using pounds. There are two sheets for you to do, the White Rose sheet and a challenge sheet. There is also a video to watch.

I've included the answer sheet so that you can check your answers (always a good habit to get into), please send your work to me when you have completed it, I am always keen to see how you are getting on. 

8.1.21

Order the groups of numbers, don't forget to order them using the Hundreds first. If the Hundreds are the same order the numbers using the Tens digit, and if the H's & T's are the same sort them using the Ones.
Be careful with Q7, it has some 4 digit numbers! 

7.1.21

Here is a task that will use your place value skills
(remember with < & > the crocodile eats the biggest number).

6.1.21

Please complete section B and , if you can, the first part of section C (Qs 1 to 12). You can do all of C too if you would like to.
If section B is a bit too hard, please don't worry, try section A.
You don't have to print the sheet out, you could write your answers on a piece of paper, take a photograph and send that to me.

Aut3.10.2 - Make equal groups - grouping

Multiply by 4

There is no Powerpoint for this today, so we will have a look at it in the Zoom. It is just another way to practise, and strengthen your times table knowledge. 

Aut3.9.3 - Using arrays

Multiplication - equal groups recap

Aut3.6.5 - Mixed addition and subtraction problems

Remember to read the question twice, look for the important information and then decide what to do.
