What is 1?

What is 1? is a simple and engaging book that helps children understand numbers in a fun and meaningful way. Through this rhyming composition, kids explore two key ideas in counting: abstracting (understanding that numbers can represent different things) and unitizing (seeing groups of things as single units).

The book introduces a powerful concept: the number 1 can represent anything

This flexible thinking about the number 1 can open up many new ways for children to learn and enjoy mathematics as they move through school. It may encourage creative problem-solving and flexible thinking, which are essential skills in mathematics and beyond.
