Bring number sense to life with the CESA 6 Open Number Line Cards, a versatile, interactive math tool designed to deepen students’ understanding of numerical relationships.
Sets designed for grades K-5, these cards invite students to explore whole numbers, fractions, decimals, and more by physically placing cards along a rope or line, sparking meaningful discussions about value, spacing, and scale.
Rooted in best practices from the Standards for Mathematical Practice and supports the work of Chris Shore author of Clothesline Math The Master Number Sense Maker. This activity prioritizes reasoning and student dialogue over exact answers. Students compare quantities, defend placements, and refine their thinking while visually seeing how numbers relate linearly.
Each set includes:
- Ready-to-print number line cards
- Blank cards for customization
- Teacher directions with facilitation tips and question prompts
Whether using benchmark numbers or mixing representations like ten frames and tallies in the lower grades or fractions pictures and decimal cards in the upper elementary grades, the Open Number Line Cards support all learners in developing confidence and precision with numbers.
Ideal For:
Elementary teachers, interventionists, and math specialists seeking a hands-on, collaborative way to build number sense.
