*“…the understanding of number patterns and the logic to the naming systems and values of number” *

**Place Value Micro Content**

- Order of digits makes a difference
- Additive property – The quantity represented by the whole numeral is the sum of the values represented by the individual digits
- Positional property – The quantities represented by the individual digits are determined by the position they hold within the whole numeral
- Base 10 property – The value of columns or positions increases by a power of 10 moving right to left and decreases by a power of 10 moving from left to right
- Multiplicative property – The value of a number is determined by the products of its face and place values
- There are patterns in the way we read and say numbers
- There are patterns in the way we write numbers
- Patterns in the number system can help us build other numbers
- Place value columns have names
- Zero can hold a place
- A 10 group is seen as a special entity which can be counted
- The term 10 group can be applies to ‘ten tens’ or ‘ten hundreds’ and so on
- We can skip count by ten, hundred etc. both forwards and backwards in place value parts
- Numbers can be partitioned in flexible ways using standard and non-standard partitions
- Number partitioning can be shown as indicative of digit value and place value. For example, 26=20 + 6 or (2×10) + (6×1)
