TRANSCRIPT
How have things changed…
Children being taught how to use a range of methods with practical resources to help develop their understanding
Children having time to talk together about their work
Children sharing their methods with the teacher and each other
Children being taught how to work mentally
Teaching and learning that is always built on what children have already learned

Tracks and number lines

The beadstring may be used to model the following strategies:- Doubling- Counting forwards and backwards- Using the relationship between addition and subtraction- Number facts- Partitioning

On the move
Make a tower with Multilink (1 – 10)
Find a partner
With the same number in their tower
So towers have a difference of 3
So that if you subtract one tower from
the other you are left with 2
So that if you count back from one tower to
another the difference is 4.
The baker makes 54 loaves and sells 28.
How many has he left?
54 - 28
30 34 54
- 4- 20
26 loaves are left
- 4

Using the number line and bridging to count back
Key Principles
• Every day is a mental mathematics day• Hands-on learning is still important• Seeing mathematics through models and
images supports learning• Talking mathematics clarifies and refines
thinking• Make mathematics interesting• Learning from mistakes should build up
children’s confidence
Addition and subtraction activities at home
• calculating change - which coins, different combinations• deciding on coins to pay a bill• weighing fruit and vegetables in the supermarket• counting pocket money• calculating the price of a holiday from brochures• estimating the final bill at the end of shopping while waiting
at the checkout• calculating discounts e.g. 20% reduction, 50% sale price• using shopping bills to calculate change• calculating postage on letters using first or second class
stamps• calculating the cost of a meal using a menu• calculating the cost of the contents of a lunch box• using the till receipt to check the shopping• calculating the cost of the family going to the cinema,
swimming baths, etc
How can parents help…..
Talking about mathematics in everyday situations:
• counting when climbing the stairs, laying the table, shopping,
planning an outing, solving problems
Playing games:
• Snakes and ladders, Ludo, draughts
• Guess who?, Connect 4, Dominoes
• Snap, Happy Families
If they are stuck useful questions:
• What have you got to do?
• How have you started?
• What have you found out so far?
