Early Number relationships
• Spatial relationships: children can learn to
recognise sets of objects in patterned
arrangements and tell how many without
counting.
One and two more, one and two less
• The two more than and two less than relationships
involve more than just the ability to count on two or
count back two. Children should know that 7, for
example is 1 more than 6 and also 2 less than 9.
Anchors or “benchmarks” of 5 and 10
• An understanding of ten is vital in our numeration
system and because two fives make up 10, it is very
useful to develop relationships for the numbers 1 to 10
to the important anchors of 5 and 10
Part – Part – Whole Relationships
• To conceptualize a number as being made up
of two or more parts is the most important
relationship that can be developed about
numbers.
Subitizing
Being able to instantly recognise a pattern
Children need to be able to subitise and explain
what they saw and tell what they know
