# Numeracy

Welcome

Please find, on this page, the core areas of Numeracy which are covered each week in P3. Each section below will contain an activity to be completed weekly. The activities can either be accessed here or will be found in booklets which have been sent home.

These resources follow the schemes of work covered in P3. If you wish to extend your child's learning please do so based on the content covered on this site.

You will find support materials, including a range of interactive games, to guide your instruction in the Helpful Resources section of the P3 site.

Many Thanks,

S. Black and L. Neill

Week beginning 11th May 2020

Daily Mental Maths

Daily Mental Maths Booklets are a great resource to help revise and reinforce taught mental maths skills.

Children should complete 1 column per day (Mon - Fri) in their Mental Maths Activity Booklet.

Tables

Children are, as normal, being asked to learn 1 Number Story per week.

Each story is laid out in your child's Number Stories Booklet which they have received home with them.

Please learn only 1 story per week;

E.G. Week 1 - 14 addition

Week 2 - 14 subtraction

This week your child should learn number stories:

Group 1 – stories 16 subtraction

Group 2 - stories 14 addition

Number Work

In this section we will set out the number work activities as we would teach the children each week.

1. Children will have a mental maths objective to cover each week. This will help to improve quick number recall.

2.  Children will have a written numeracy activity to complete each day. This will either be in the form of an uploaded worksheet or will be pages from the New Heinemann Maths (NHM) booklets which have been sent home.

Mental Maths Objective

Mentally subtract a multiple of ten from any number within 100

For example:

Subtract 30 from 46 = 16

50 takeaway 86 = 36

20 less than 57 = 37

Some strategies the children can use are:-

Children could count back in tens to find the answer.

For example

44 – 30 =

Put 44 in your head and count back three tens – 44 to 34 then to 24 and then to 14 – the answer is 14.

OR

Look at the 2-digit number as the number of tens and ones.

For example

44 – 30 = is the same as 4 tens take away 3 tens = 1 ten which is the same as saying 14.

REMEMBER when taking away multiples of ten the ones/units stay the same.

Number Work Activity 1

Number Stories

Group 1 Complete one activity related to the story of 16

Group 2 Complete one activity related to the story of 14

Number Work Activity 2

Subtracting tens and ones/units

When completing the subtraction questions-

1. Subtract the ones/units
2. Subtract the tens
3. Add the two totals together.

For example:

46 - 24 =

6 - 4 = 2

40 - 20 = 20

20 + 2 = 22

Complete page 23 in the NHM Addition and Subtraction to 100

Number Work Activity 3

Subtracting tens and ones/units

When completing the subtraction questions-

1. Subtract the ones/units
2. Subtract the tens
3. Add the two totals together.

For example:

79 - 35 =

9 - 5 = 4

70 - 30 = 40

40 + 4 = 44

Complete both worksheets

Topic Work

Topic Maths includes Shape and Space, Measures and Data Handling.

We complete 1 piece of Topic Maths per week.

Topic Maths Activity

Fractions – Halves of Shapes

Starter

Ask your child to suggest what happens when a cake or pizza is cut ‘in half’ or ‘halved’.

How many pieces are there?

What size are the pieces compared to each other?

Hopefully they will understand that halving produces 2 pieces of equal size.

Activity

Take a piece of A4 paper and fold in half.  While folding, emphasise the importance of ensuring that the edges of the paper are placed together as exactly as possible.  Open out the paper and write on each half the words - ONE HALF.

Ask your child how many halves have been made.  Ask them to describe the size and shape of the halves – they are the same.  Emphasise that halving produces 2 equal parts.

Repeat with another piece of A4 paper but fold in half a different way to show that it produces 2 equal parts. Write on each half – ½ to show another way to write half.  Please explain that ½ means 1 of the 2 equal parts.

Fractions – Halves of Numbers

Starter

Get 8 small objects such as pasta, buttons or small sweets. Display the objects in 2 rows of 4.  Put 4 on top and 4 on the bottom.  This is called an array.

Ask the children how many objects there are.  Position a ruler to halve the array/objects.

Ask what addition fact this shows – 4 + 4 = 8

Double 4 is 8, so half of 8 is 4.

Or

Double 4 is 8, so ½ of 8 is 4

Now display 6 pieces in one row.

Now ask which ‘double’ and ‘half’ this shows:-

Double 3 is 6

Half of 6 is 3

½ of 6 is 3

Repeat for other doubles such as 2 + 2 and 5 + 5 to establish a link between doubles and halves.
