Purpose
The purpose of this activity is to support students in understanding that tens are nested in hundreds, and ones are nested in both tens and hundreds. They also develop fluency in renaming three-digit numbers in multiple ways.
Required Resource Materials
- Place value materials: individual items grouped into tens, such as BeaNZ in film canisters, ice block sticks bundled with rubber bands (hundreds with hair ties), or a paper form such as Place Value People. Bundled materials are important as they allow partitioning and combining without the need for “trading” tens blocks for ones.
- Calculators
- Use a place value board to organise the materials in columns and support calculation strategies. A three-column place value board is available here.
