Key learning points
- The digits in a number indicate its structure so it can be decomposed.
- Numbers can be decomposed, or partitioned, according to the value of their digits.
- Missing parts can be determined by comparison of known parts to the whole.
Common misconception
A child may give the incorrect value for a digit or struggle to see how to partition larger numbers in a non-standard way.
Use a place value chart or counters to prove the value of the digit and use a Gattegno chart to support partitioning.
