This versatile tool, designed to be used with standard 1-centimeter base ten blocks (units and rods of 10), helps students visualize and solve operations, ratio, and percent problems.

The durable 1 cm foam number line is 4" high by 21" long and has dual channels that can hold up to 50 base ten units each and a dry-erase writing surface.

The dual channels provide students the ability to represent and model equations and problems in a structured, meaningful way.

Includes teaching notes with sample activities for CCSS.

Does not include base ten blocks or rods.
