3. Aims of the session: Enjoy maths and play around with numbers.
Learn a little about how we teach maths across KS1.
Learn how we teach:
Addition
Subtraction
Multiplication
Division

4. KS1 Practise Makes Permanent
“The Principle focus of mathematics teaching in Key Stage 1 is to ensure that pupils develop confidence and mental fluency with whole numbers, counting and place value. This should involve working with numerals, words and the four operations, including with practical resources (for e.g. concrete objects and measuring tools). An emphasis on practice at this early stage will aid fluency.” DfE 2013

5. Maths in KS1 at Applecroft School
Fun and something to be played with
Relevant to everyday life and especially the children’s everyday life.
Involves practical and oral/mental work as well as ‘traditional’ book work.
Taught once a day for between 20 and 60 minutes.
Contained within a 3 part lesson : Oral/mental starter
Main activity
Plenary
Is supported by numerous additional sessions for booster and enhancement.
Challenging.

6. What Maths do we teach in KS1?
Number bonds from 10 and 20 ( ie 7+3=10, 18+2= 20)
Place value ( units, tens and hundreds)
Addition and subtraction to 100
Basic multiplication ( 2,5,10)
Basic division ( dividing into 2, sharing into groups)
Fractions ( ½ , ¼, 1/3 3/4)
Time ( o’clock, half past, quarter to, quarter past)
Measurement ( weight, length, capacity)
Money ( everyday money- calculating change)
Problem solving
Handling data ( graphing, tables, sorting data)
Shape and space
Today we will focus on the red highlighted examples

7. Understanding number
The ‘eightness’ of eight!

8. Place Value We use place value cards
in combination with unifix cubes and
100 squares to recognize
values of numbers.
i.e. make the number 245
Step 1: separate the to its value
2 hundreds, 4 tens and 5 units
Step 2: make that number with either cubes or a value card.

9. Oral and Mental
Children are encouraged to develop mental strategies to solve calculations.
Rapid recall of number facts (number bonds, times tables, doubling, halving)
Big Maths carried out weekly
Lets have a go!

12. Your Turn
Big Maths…Beat That (Y6 questions)

13. Resources Number line Counters Unifix cubes Number square
Place value cards
Dienne rods

14. Year 1 and Y2 Objectives + & -
Mental Calculation – see sheet
Written Methods – see sheet
See Planning on a Page

15. Addition and Subtraction
Counting
Using known number facts- near doubles, compensating
Mental methods including jottings
Largest number first
Number lines – compensation, bridging through 10, partitioning.
Children are shown a variety of strategies so they can make the choice when it comes to solving a problem.

24. Addition and Subtraction a with number square
Adding 12
54 +12= 66
Step 1 :Partition the number
( one 10, two units) 10 & 2
Step 2: add on the 10 ( down 1)
Step 3 add on the units ( right 2)
Adding 10 go down 1
Subtracting 10 up 1
Adding 1go right 1
Subtracting 1 go left 1

25. Addition and Subtraction a with number square
Adding 9 :
25 + 9= 34
Step 1: find 25 on number square
Step 2: simplify the equation ( add 10 -1).
To add 10 simple go down one on the number
Grid then then take 1 to make 9 ( go left 1 space)
Down 1 left 1
Subtracting 9:
25 -9= 16
Step 1: find 25 on the number grid
Step 2: simplify the equation ( take 10 +1)
Step 3: to take ten go up 1 then take 1 by going
Right 1.
Up 1 right 1

26. Multiplication Written calculations: Models & images: Mental

27. Using a number grid for patterns and multiplication
Colour in the
even numbers to recognize odd and even
Learn the 2, 5 and 10 x table
