Transcript of Foundation Stage Mathematics - Belfast Education & …€¢ numbers increase as you count up 3....
Aims By the end of the session participants will: 1. Appreciate the importance in creating a positive
environment for maths; 2. Explore the mathematical learning potential with
sorting, and 3. Appreciate the importance of counting in relation
to all aspects of number.

The learning environment in mathematics
Gemma, aged 7, Year three
Her teacher thought that Gemma had a good understanding of the equals sign. Gemma had no problem with sums like 2 + 3 = , and even 6 + = 9. Then the teacher asked Gemma how she did 2 + = 6.
Gemma replied, “I said to myself, two, (then counting on her fingers) three, four, five, six and so the answer is four. Sometimes I do them the other way round, but it doesn’t make any difference”. She pointed to 1 + = 10. “ For this one I did ten and one, and that’s eleven.”
How does Gemma show here that she has some understanding of the concept of addition? What about her understanding of the concept represented by the equals sign? How would you analyse the misunderstanding shown at the end of the conversation?
What do we want for our children in terms of mathematics when they leave the
primary school after seven years?

Counting We want to consider • The issues with counting? • How does equivalence affect counting? • How does the idea of transformation
affect counting?
Progression through counting
Pre counting experiences
Level One
When adding count on in ones:
• within 5
• within 10
When subtracting count back in ones:
• within 5
• within 10
Level two
When adding or subtracting count on or back in:
• ones
• tens
Pre counting experiences 1. Sorting and classifying
• separating off the objects which need to be counted
• these objects to be counted have an element of equivalence
e.g. ‘How many children are here today?’ the children know not to include the adults
2. ‘One more’ ‘Another one’
• numbers increase as you count up
3. Distinguishing between small numbers without having to count
• They know they have two feet; two eyes; one nose
Counting in Foundation Stage The five principles of counting 1. Stable order 2. Order irrelevance 3. One to one 4. Cardinal 5. Abstract
Eventually children will associate the number word with the numeral.
I was asking a child in year two what number is one more than six.
He couldn’t do it. But he could count up to 20 and beyond.
1. The idea that the next number in the counting sequence is one more than the previous number is a vital component to understanding number
2. The complementary idea that the previous number is one less is equally as important.
Before and after
The children need experiences of the ordinal aspect of number just as much as the cardinal. Using number lines, number tracks, number ladders will help this. Spend time on - one more - one less - after - before - and another one
Sorting develops mathematical ideas
• Observation • Reasoning • Language • Cardinal number • Equivalence – comparing equal sets • Difference – comparing unequal sets for more
than/less than • Conservation • Component of number • Concept of zero
Difficulties arising from limited experiences
• Unable to select their own criteria • Unable to tell you the number of
objects in a set • Difficulties sorting for anything other
than colour • Unable to talk about their decisions • Unable to make choices for
themselves
Progression through sorting
• Undirected/random sorting • One property collections • Two property collections • Three property collections • Partitioning

Two property collection
Sort for • Shape and colour • Shape and size • Shape and thickness • Colour and size • Colour and thickness • Size and thickness
Partitioning
• To partition is to divide a set into subsets • Partitioning is early component work • Children are ready to partition when they can count a collection of objects they can recognise the numerals they have conservation of number up to 5 they can resort a collection
Partitioning • Teacher needs to use carefully selected
sets • Children need to realise they are working
with the same set of objects each time
