Maths support

This maths page has lots of links to interactive resources, to support your child to learn some areas of maths that they need to practice. They can pick and choose, according to what they think they need to do. Of course it's a good idea for them to practice things they are confident with too, but challenge is good for growing our brains!

Learning to tell the time

This post is full of resources to help your children learn to tell the time. We would teach it in the following sequence at school:

Time to o' clock (recognising long and short hand) This youtube video is a good basic starter.
Time to the half hour (understanding the short hand shows the hour and that it will travel between the hours on an analogue clock)
Time to the quarter hour
Time to the nearest 5 minutes. We would link this to times tables knowledge. The concept of to the hour is more difficult than past the hour. There is a video here that might help
Time to the nearest minute. (The concept of to the hour is more difficult than past the hour.)
The concept of am and pm
Digital times and how they relate to analogue
The 24 hour clock - converting between 12 and 24 hour clock
Timetables (e.g. train, television schedules)

Throughout these, we would interweave problems. Once children are confident with telling the time, we would add time intervals, e.g. How many minutes until something happens; it takes 20 minutes to walk to school. I need to be there at 10 past 9. What time should I leave home?

These resources should help


Interactive games from Topmarks

Snappy maths has a range of different worksheets for printing and lots of links to interactive games if you scroll down

BBc bitesize What is time?

Nrich problems these require the children to use their mathematical knowledge, perseverance and stamina. They will need to draw on a range of skills and strategies.

Measuring

Measuring around your house!

1. Pick 5 small objects that you could easily measure the length of.
2. Put them in order from smallest to largest.
3. Look carefully at your measuring tool and find 10 cm. Decide which of your objects are bigger or smaller than 10cm. (Try to remember the size of 10cm, using your fingers).
4. Estimate the size of each object, in cm, then write down your estimates.
5. Now measure them accurately. Think about some golden rules for measuring beforehand ( look at the end of this post and see how many you thought of). You could measure them to the nearest cm, half cm or nearest millimetre. Check your estimates. How good were they? (It doesn't matter if they were a long way off, you will get better at this!)
6. Convert your measurement from cm to mm. You could do it by using your knowledge of x10, or by doing it this way:

If your object measures 10 cm and 3 mm, convert the 10 cm first. 1cm = 10mm (look at the mm in your measuring tool to prove it), so 2cm must = 20mm and so on. Carry on with this pattern until you find how many mm there are in 10cm. Does this remind you of anything? (Yes, it’s the 10x tables!) When you have found the answer, add on yout 3mm. Remember that if an object is 13cm, you will have to do 13 lots of 10mm, before adding the rest on.

7. Now pick some bigger objects and do exactly the same thing with them. Make sure you estimate first - it is a great skill to keep practising and it doesn’t matter if you are not right, because you will get better with practice! You might not be able to put these in order in your house, but you could say which ones you think are smaller / bigger.

When you have done that, think of some things that you might have to measure around the house. This week I have measured my kitchen, for new worktops. I have also measured BeauBeans for a new running harness. He has a big neck!

Extra challenge

Add some of the measurements together (your choice which ones or how many you add). Look around the house and find something that you think will be the same length as those combined lengths. How close were you? Reflect on your estimating skills. Repeat! 



Miss BB’s Golden rules for measuring

1. Select the right measuring tool for the job! You can’t measure a finger nail with a trundle wheel accurately!
2. Make sure you start at 0. Some rulers don’t have 0 on the end.
3. Make sure you use the right unit of measurement. Don’t accidentally use inches if you are measuring in cms. Don’t use km for small objects.
4. Estimate what you think the measurement would be. That way, if your estimate and actual measurement are very different, you might realise you made a mistake with your measuring.
5. Measure twice, or get someone to check your measurement. It’s easy to make mistakes! 
6. Write down your measurement, so you don't forget it if you are measuring lots of things.
7. Look at the measurement you have written down. Does it seem right? 

Maths for Wednesday

Tuesday maths

Watch the tutorial to remind yourself how to do 2-digit by 1-digit multiplication.

Then have a look at 3-digit x 1-digit if you are confident with this.

To make your multiplications harder, follow the rules for picking numbers below. Write 6 multiplications to try, then get someone to check them. Try to estimate where you think your answers will be, before you start, then check your answers are sensible once you have done them. 

Chilli 1 - 2-digit numbers multiplied by 2,3,4 or 5

E.g. 23 x 4

56 x 3

Chilli 2 - 2-digit numbers x 4, 6, 7, 8 and 9

E.g. 23 x 7

56 x 4

Chilli 3 - 3-digit numbers x 2, 3, 4 or 5

E.g. 223 x 4

156 x 3

Chilli 3+ - 3-digit numbers x 4, 6, 7, 8 or 9

E.g. 523 x 7

156 x 6

Monday maths challenges!

Activity 1

Work out the answer from the clues below.

 Investigation 2



Use some dice, or the dice online here https://www.random.org/dice/?num=3 . Roll 3 dice and multiply the numbers together. Now swap the numbers around. Do you always get the same answer? Test it out at least 5 times to prove it! Were some calculations trickier than others? If so, why? Were some easier? Why? (That will help your metacognitive thinking, which will help your learning!)

After that, have a go at rolling the dice 3 times again, then multiplying your answer by 10. Remember your place value and how x10 relates to it.

If you find it tricky, use this resource to help https://www.topmarks.co.uk/Flash.aspx?f=MovingDigitCards (if you can't get flash to work, click on the padlock in the address bar, which should give you the option to enable flash).

Investigation 3 (optional!) 

Write the numbers from 3  - 12 on scraps of paper and turn them upside down. Pick 3 and multiply them together. Can you do them all mentally, or do you need to do it another way, like repeated addition or drawing a multiplication grid? Which ones were easy / hard? Why?

Remember that you are allowed to jot things down on paper, even when working mentally! Writing things down helps you learn to do them in your head.

Subtraction support

Watch this tutorial to help you subtract from a multiple of 10

Now have a go at this, for subtracting from multiples of 100 or 1000. Pause the video to make sure you really understand the first part, about the difference between two numbers. Get out some beads, coins, pasta or something so that you can prove it, by physically moving things. If it makes your brain too fuzzy, don’t worry! We will do it again when we are back at school.

Thursday maths

Subtraction problems


For your maths today, select the right chilli challenge for you. You can either pick one of the sheets, or problems from the group of sheets.

 You do not need to do all the questions, but you need to do at least 6. If you want to keep going, that's fine! Make sure you read carefully and look for the clues (the important words) in the problems. Draw the story if you need to. Use columns to subtract, then write your answer in words. The answers are on the second page of the first files. For the word document (the mixed problems), you will have to get an adult to check with you.

Chilli 1 problems
Chilli 2 problems
Chilli 3 problems
Chilli 3+ problems

Alternative Chilli 1, 2 and 3 problems

(If you have difficulty accessing these files, they are also in the folders section of Edmodo)


Look back at the class grid for your English work and other activities.

Subtraction, Wednesday 29th April

Watch the tutorial if you need a reminder about subtraction. Remember that we call it exchange, not borrowing (we are exchanging 1 ten for 10 ones, or 100 for 10 tens etc)

Pick the challenge that is right for you! If it is too easy, have a go at the next challenge. Make sure you look for the exchanges before you start calculating (make sure most of your calculations have exchanges!). Remember to write your calculations as columns.

Chilli 1: 2-digit numbers take away 2-digit numbers e.g. 76 - 38 =

Chilli 2: 3-digit numbers take away 2 or 3-digit numbers e.g. 457 - 88 =          534 - 286 =

Chilli 3: 4 - digit numbers take away 3-digit or 4-digit numbers e.g. 7236 - 1879=         7236 - 768=



English

As well as the activity on the grid, make sure that you read to someone today and think carefully about what you have read (make sure you understand!)

Tuesday 28th April

Once you have completed your maths on the grid, have a go at these problems. Remember to read carefully, draw things in your book if needed, talk about them and think!

If you want to do some more maths after this, check out the sumdog challenges.

Come back to the blog later for the pictures for English.

Thursday 23rd April

Good morning lovelies! Hope you are all ready and raring to go! Don't forget to warm your maths brains up with some counting activities (maybe whilst exercising?) or times tables, or Sumdog.

Pick the chilli challenge that's right for you, from the link below. The answers are there, ready for when you have finished them, so you can check your own, If you get one wrong, go back and try to find out why. Remember, that's the best kind of learning!

Click on the link for your chosen chilli challenge.

Chilli 1

Chilli 2

Chilli 3

You need to practise subtracting with chilli 3 too!

Extension activity

Click on the picture to enlarge it if needed

Here's that metacognitive bit! Evaluate how you did. What made it easy / hard. What strategies did you use? Were they successful? What helped? You don't have to write these answers, you could think them or talk to your family. This is an important part of you knowing yourself as a learner and becoming an even better mathmatician!

Wednesday 22nd April

Use the tutorials to help with your maths today, if you need them.

The first is for tens and ones, the second video covers thousands, hundreds, tens and ones.

Even better than addition (though probably not as mathematical) is Mr Gum and the Biscuit Biliionaire, read by the actual, real life, not Miss BB in dressing up clothes, Sir Andy Stanton! Enjoy! (You can even save it for PJ and duvet time. Or just put your PJs on?)

Maths puzzles

This week we have been thinking about how we learn in maths. We know that everyone has the potential to be goods in maths and that if we think we are not good, it's because of the experiences that we have already had. We know that sometimes maths is tricky and makes us get fuzzy brain, but overcoming this fuzziness helps us learn and become even better mathematicians.

Today we have been looking for patterns, then explaining what we can see. There was a lovely buzz in the room whilst the children were exploring these.
