# Numeracy

The following are some areas of Numeracy that we cover each week in Primary Four.

The activities mentioned are either attached as downloadable/reference documents (big pics) or have been sent home in booklet form (small pics).

Please resist the temptation to work ahead of what is recommended each week as, if we return to school before the end of June, we will try to pick up from the point we have covered on this site.  If you find that your child copes particularly well with any task, please avail of the ideas in the Other Resources section of the P4 site or the links at the bottom of the main Home School Resources page to extend their learning and practise skills in different ways.

Thank you,

Miss L. Neill and Mrs R. Millar

Mental Maths (daily)

The Daily Mental Maths Book activity covers a wide range of skills and should be read and completed independently.

Mon- Fri (pg 68 & 69)

Tables (daily)

The tables for the week should be practised and rote learned for rapid and accurate recall.

The children know that multiplication is repeated addition and have shown their understanding of this in class.

They now need to use that knowledge in reverse to generate the answers to the division tables!

We will continue by looking at the ÷4 tables.

Multiplication and division are linked in the same way that addition and subtraction are.

Practise by saying your x4 tables first.

1 x 4 = 4       ...so...    4 ÷ 4 = 1

2 x 4 = 8       ...so...    8 ÷ 4 = 2

3 x 4 = 12     ...so...   12 ÷ 4 = 3

4 x 4 = 16     ...so...   16 ÷ 4 = 4

5 x 4 = 20     ...so...   20 ÷ 4 = 5

6 x 4 = 24     ...so...   24 ÷ 4 = 6

7 x 4 = 28     ...so...   28 ÷ 4 = 7

8 x 4 = 32     ...so...   32 ÷ 4 = 8

9 x 4 = 36     ...so...   36 ÷ 4 = 9

10 x 4 = 40   ...so...   40 ÷ 4 = 10

Have a go at the activities below to help introduce the ÷4 facts and practise them in a fun way.

Monday

In the next few weeks we will be continuing to add to our facts until we have covered x1/x2/x3/x4/x5/x10 and the related division facts. Many of these activities will be taken from the NHM3 Assessment Book.

Keep going over these at every opportunity so that you hardly have to even think about the answer!

Get some cubes, counters, pieces of pasta or even Smarties and an appropriate number of plates to help with these pages of division work about dividing by 4.

When we were multiplying, we were counting in equal groups.

When we are beginning to divide, we have to also have equal groups.

Tuesday

Set out neatly with 'date' and 'w.a.l.t.:divide by 4.

Wednesday

Have a go at the dividing by 4 space race track below.

How long do you think it will take you?

How long did it actually take you?

Thursday

As with Tuesday's activity, don't forget to read the page carefully and talk to an adult about what you have to do.

Set out neatly with 'date' and 'w.a.l.t.:divide by 4.

Numberwork (Mon and Tues)

There will be two main pieces of Numberwork each week which we usually complete on a Mon and Tues.

Revision Place Value - Hundreds, Tens and Units (Mon)

This work reinforces work covered before Lockdown on HTU numbers.

It would be good to spend a little bit of time revisiting this before we move to the addition and subtraction of HTU numbers in the coming weeks.

Complete activities below which from the NHM3 Assessment Book pg 3 & 4

Read each question carefully and decide what you have to do with each number.

Revision Place Value - Hundreds, Tens and Units (Tues)

Complete activities below which from the NHM3 Assessment Book pg 1a & 1b (pages with red border)

Read each question carefully and decide what you have to do with each number.

Measures, Shape & Space and Handling Data (Wed)

Time

How did you get on over the last couple of weeks with the introduction of 5 minute intervals?

Remember that it  can be quite tricky and will be revised in P5 so just try your best and give yourself time for lots of practice over the summer.

Weight

This week we are moving on from time work to look at measures.

We can measure lots of things in various ways and using various things.

Have a look at the PowerPoint below to help remind you of some of these ways.

Then have a look at the Text Book pages.

Have a chat about pg 86, no need to write anything down.

Think about the balancing scales and why one side is lower/higher than the other.

Have a go at the challenge to find something in your house or garden that is between 2kg and 3kg.

(If you don't have scales you could find something that says the weight on the packet.)

kg (kilogram)

g (gram)

1kg = 1000g

3/4 kg = 750g

1/2 kg = 500g

1/4 kg = 250g

so...1/2 kg + 1/2 kg = 1 kg

1 1/2 kg = 1000g + 500g = 1500g etc.

Then have a look at pg 87 & 88.

Do as much as you can of pg 87 given your equipment.

Then have a go at pg 88 which uses the items and weights at the top of the page.

Remember, this is new learning and will be revisited in P5 so don't worry if it's a bit tricky.

Just have fun with estimating and weighing to see if you are close in any of your guesses.
