1-to-20 Laminated Number Line
Number lines are important in helping children to develop number sense and helping them to visualize the numbers in relationship to one another. These number lines are made to work with our blocks - the unit size is the same. Like the wooden number track they are laid out in sections of 10, each representing a decade. With different blocks, they can be used to visualize and conceptualize addition, subtraction, multiplication, and division.
