Things come in different sizes. An elephant is big. A mouse is small. Which ball is the biggest? Which is the smallest?
Key idea
Big, bigger, biggest. Small, smaller, smallest.
For the grown-up: Line up three things of the same kind but different sizes: spoons, shoes or bowls. Ask which is biggest and smallest. Size words are math words. Short and happy beats long. Five minutes is a good lesson.
- Try it at home: Line up family shoes from small to big.
- Nest measuring cups or bowls.
- Find a big leaf and a small leaf.
