Step One: Gather materials.
Step Two: Sort.
- Place the Duplo Blocks into several piles separated by color.
Step Three: Estimate.
- Estimate which color pile had the most blocks.
- Estimate which color pile has the least blocks.
- Talk about which color piles look roughly the same size.
Step Four: Have the child check their estimates by counting the piles of Duplo Blocks.
Step Five: Have the child build objects (using creativity) with the Duplo Blocks.
