Maths

Week Beginning: 10th June 2018

This week we are learning how to:

1. Multiply using the formal written method.  Previously, we have used the expanded method and now we are moving onto the compact method.  Here is a video to show you how we teach it!  https://www.youtube.com/watch?v=eUUrV5onhyo

2. Divide using the formal written method.  Previously, we have used the bus stop method with numbers that can divided by the number exactly.  This week we are going to be finding remainders.  Here is a video explaining it https://www.youtube.com/watch?v=FApcjdAhnrY  Watch for the first minute only as the rest is taught further up the school.

3. Make quarter, three quarter and half turns.

Week Commencing: 7th May 2018

This week we are learning how to add and subtract fractions.  Again I have put the powerpoint below as this is what the homework is based on.  Just remember to emphasise that it is the numerator we add or subtract NOT the denominator.  We are also looking again at 3D shapes and their properties as they struggled with this last time.

Week Commencing: 30th April 2018

This week we are learning about equivalent fractions.  We have learned that sometimes fractions have the same amount shaded, for example 3/6 can also be 1/2.  We also learned how to multiply and divide the numerator and denominator to find other equivalent fractions, for example with 4/12 we know that 4 goes in each one so it could be 1/3.  Below is the powerpoint we used to explain equivalent fractions.

Week Commencing 23rd April 2018

This week we are looking at fractions.  We are focussing on the numerator and denominator and what they both mean.  The bottom number is the denominator and tells you how many parts there are and the numerator tells you how many parts you are focussing on.  An example of this would be: ¼ of 24 = 6.  24 is split into 4 parts and there are 6 in one part.  2/4 of 24 would be 12 as 24 is split into 4 parts and there are 12 in 2 parts.  The homework is based on this.  It is double sided so please do both.

Week Commencing: 16th April 2018

This week we are learning about time and the children really do find this very hard.  They will need a lot of practise at home to consolidate this. These are the three skills we will be learning:-

1. How to tell the time using Roman numerals.

2. How to tell the time to the exact minute, for example 22 minutes to 3 or 12 minutes past 4.

3.  How to convert the 12 hour clock to the 24 hour clock, for example 3:10pm would be 15:10 in the 24 hour clock and 4.20am would be 04:20 in the 24 hour clock.  They do find this tricky, especially the am times!

Below are some powerpoints that might help.  Please practise skills 2 and 3 at home.  In terms of their homework, they can write the time in words (i.e. 5 minutes to 3) or digitally (2:55), it is up to them and what they feel most comfortable with.

Week Commencing: 12th March 2018

This week we are learning about 3D shapes and will be looking at the names and properties of them by making them out of card and labelling them. This is what the homework is based on. If they are finding this difficult, try using 3D shapes from around the house so that they can count the vertices (corners), edges and faces. Finally, we looked at turns and how two right angle turns is 1/2, 3 right angle turns is ¾ and 1 right angle turn is ¼.

Week Commencing: 5th March 2018

This week we are focussing on division and learning about the formal written method which is also known as the 'bus stop' method. Please see the route through calculation on the front page of the Year 3 page to show you how we do it.  Please be aware, however, that we are not learning about remainders until the summer term.  This is a challenging concept for them.  The homework is all about seeing the relationships between multiplication and division and realising that they are interlinked.  If they are struggling, remind them that with multiplication, the big number goes at the end and with division, it goes at the start.

Week Commencing: 26th February 2018

This week we are completing work on multiplication using the formal written method.  We will teach them how to do this using the expanded method. This is what their homework is about and there are instructions for how to do this on the front sheet of paper. There is also a good video you can watch: https://www.youtube.com/watch?v=MFSf52TFBwo but only watch the first minute as we do not do 3 digits by 1 digit yet! Hopefully with this video and the intructions on the sheet, they will get this! If you do it this weekend, it will hopefully be fresh in their heads! The children will probably find this hard but unfortunately this is a skill they have to know by the end of year 3.

Week Commencing: 12th February 2018

This week we are completing the end of half term testing.  We are also learning about mass.  We will be weighing items and then answering questions using the data based on addition and subtraction.

Week Commencing: 5th February 2018

This week we are continuing our work on capacity and are going to subtract capacities.  We are then going to move onto length and will measure each other's hands, legs, arms, head etc and then compare the lengths working on addition and subtraction.

Week Commencing: 29th January 2018

This week, the children have been learning about adding and subtracting 1, 10, 100 to a number and finding the missing number.  They always find this very difficult as they struggle with basic calculations, for example, 27+4.  They often make careless mistakes when crossing the boundaries i.e. knowing that the answer will be in the 30s.  They can also struggle with place value and knowing where the numbers fit in.  For homework I have given a missing number activity and there are instructions to help at the top.  Please focus on what is happening to the digits when going down, up, left and right!

We also started work on capacity focusing on reading scales and adding capacities together.

Week Commencing: 22nd January 2018

This week, we are learning how to add and subtract using the formal written method using the dienes and recording it on paper.  This is what the homework is based on and you can find posters to help you below.  If you follow this step by step, the children will be able to do it.

Week Commencing: 15th January 2018

This week we are learning about the following:-

1. Counting in 50s and 100s from 0

2. Estimating where numbers go on a numberline

3. Calculating 10/100 more and 10/100 less.

The homework is based on estimating where a number goes on a numberline.

Week Commencing: 8th January 2018

In Maths, we have continued our work on shape.  We have identified parallel and perpendicular lines in shapes.  If you are not sure what these are, see the powerpoint below – this is what the homework is based on.   We have also looked at making turns using right angles and have recognised 1 right angle turn to be a quarter turn.  To end the week and our shape topic, we have learned about perimeter.

Week Commencing: 1st January 2018

In Maths, we have been looking at shape and angles. I have taught them that an angle occurs where two lines meet.  We have looked at the different angles also – there is a powerpoint underneath to help you with them and they loved this song:https://www.youtube.com/watch?v=NVuMULQjb3o.

We looked at what a right angle is and angles that are greater and less than a right angle.  The children had great difficulty with this.

They used right angle checker to see if the angle was bigger than it or smaller than it.    The homework is based on identifying a right angle.  They can use a checker to help them (a post it note or a corner of a piece of paper will do)  If anyone wants an extra challenge, they can label the acute and obtuse angles as well!

Week Commencing: 4th December 2017

This week we are finishing our work on fractions for this term and ordering them from smallest to largest.

We are also looking at 2D shape today and are drawing and labelling them according to their names and properties.

Week Commencing: 27th December 2017

We are continuing our work on fractions this week.  We are looking at finding fractions of a shape and of an object.  See below for the powerpoints we will be using to help them with this understanding.  The homework is based on this and should be quite self explanatory!

Week Commencing: 20th November 2017

This week we are continuing our work on time and the children always find this very difficult.  We have looked at the difference betweenam and pm and read the time to the exact minute.  This is an excellent video to demonstrate what I mean: https://www.youtube.com/watch?v=f1AavpvRLvo.  If you get any time at home, ask them periodically what the time is on an analogue clock as they need a lot of practise on this.  We have also looked at tenths and have counted up and down in tenths, looked at what they mean and finally have identified what 2/10, 3/10 etc are.  See the powerpoint below for more information.  This will help you with their homework!

Week Commencing: 13th November 2017

This week we are converting time from minutes into seconds.    For example if you were to convert 2 minutes and 15 seconds into seconds you would need to do the following:-

1.  Convert the minutes by multiplying the number by 60.  In this case 60 x 2 - 120 seconds

2.  Add 120 seconds and 15 seconds together.

3.  The answer would be 135 seconds.

The children also did some reasoning on this where they had to compare times.  For example, in a race Chloe took 68 seconds and David took 1 minute and 3 seconds.  Who was the quickest?  In this case, they would have to convert both into seconds so that David took 63 seconds.  Then they would have to say that David was the quickest because 63 seconds is quicker than 68.  The children often get stuck with this as they assume the highest number wins!

We also read the time on an analogue clock to the hour, half past the hour, quarter to the hour and quarter past the hour.

Week Commencing: 6th November 2017

This week we will be starting our work on telling the time.  These are the activities we have completed:

1. We have looked at time facts i.e. how many seconds in a minute, how many minutes in an hour, how many hours in a day etc.

2. We have looked at what activities can be done in a second, a minute and an hour to give an understanding of the value of each unit of time.

3.  We have looked at how much time has passed between two times and used the numberline to help us.  For example, when looking at how much time has passed between 1.45 and 3.15, this is how you would work it out

First, see if you can move any hours.  So in this example, you can jump at hour and you get to 2.45. Emphasise that you can’t jump another hour as that would be 3.45 and that would be too much.

Secondly, try and get to the next hour.  In this case it is easy as you know that there are 15 minutes to the next hour (45+15=60)

Thirdly, what’s left – in this case it is 15 minutes which is easy to see from the minutes part.

Finally, count up the jumps.  In this case 1 hr plus 15 + 15. So, it would be 1hr and 30 minutes.  Emphasise it would not be 130.

Week Commencing: 30th October 2017

This week we are dividing using arrays.  This is very similar to multiplication but this time looking at how many are in each group.  So in this case there are 18 altogether, they are divided into 3 groups and there are 6 in each group.

We have also looked at how to work them out using a numberline.

Week Commencing: 16th October 2017

This week we are learning how to multiply two numbers and we have done this in 2 ways. The first way is using arrays – see powerpoint below to show you how to do this.  This will be what the homework is based on so hopefully this will help you!

The second way is through partitioning – these are the steps we use:-

36 x 4 = 144

Step 1. 30 x 4 = 120

Step 2. 6 x 4 = 24

Step 3. 120 + 24 = 144

Week Commencing: 9th October 2017

In maths we have been learning about capacity and money.

With capacity we have learned how to read different scales in order to be able to find out how much liquid is in a container.  We have also put containers in order from the smallest amount of liquid to the largest and answered reasoning questions.  For example,  if I added 350ml to container a, would that change which had the largest amount of water?  Prove it.

Money is an excellent skill that they can practise at home.  Give them a random set of coins and see if they can count how much they have got.  Ask them reasoning questions, for example, would you rather have 108p or £1.18?  Why?  This is what we have been doing this week.

Week Commencing: 2nd October 2017

This week we have been looking at data handling and have discussed the best scales to use for pictograms and bar charts.  For example, it is not always best to use 1s as your scale, especially if there are a lot of people to collect data from.  The children have done well at this and have been able to interpret the data as well.

Week Commencing: 25th September 2017

This week we have used our knowledge of place value to put numbers on a numberline.  For example, if the start of the numberline is 600 and the end of the numberline is 700, where might 660 be?  We have talked about how it is easier to find the middle number, in this case 650 and then work backwards or forwards from there.  Sounds easy but it is quite challenging for the children.  This is what the homework is based on.

We have also started the process of teaching the children how to add and subtract using the formal written method.  Below are two posters explaining how we teach it.  Please note that we have only done this using the dienes equipment so we are not expecting them to be able to record it like this yet!

Week Ending: 23rd September 2017

This week we have been adding ones, tens and hundreds to a 3 digit number.  They have found this quite difficult.  We have used the dienes equipment to try and demonstrate what happens to each number, especially when crossing the boundaries.  For example, when working out 357 + 4, we not only have to change the units but also the tens to.  We will be continuing work on this during our mental starters as it is a very important skill.

As well as this we have been counting in 50s and recognising how it is similar to counting in 5s.  For example, 0, 50, 100, 150, 200 is similar to 0, 5, 10, 15, 20.  We have also looked at numbers and compared them, putting them in order from smallest to largest using our knowledge of place value.

Week Ending: 15th September 2017

In Maths, we have been looking a lot at place value, for example, in 458 we have focussed on what each number represents, in this case 400, 50 and 8. We have used this knowledge to add and take away 10 and 100 from a number, write numbers in words and numerals and we have partitioned numbers.  They are getting there but can find it difficult to reason using these skills.  We have also practised counting in 4s and 8s.

See below for a number generator where you can put in the starting number and the steps you want to jump and it generates numbers.  You can hide or show the numbers so it is nice to get the children to work out which one comes next!  In year 3, one of the targets is to count forwards and backwards in 4s, 8s, 50s and 100s.

The homework this week should be self explanatory!
