The Long Red Rods 5-Step set offers a condensed version of the classic length series, providing five rods rather than ten for classrooms with limited floor space or for use as an introductory material before presenting the full set. It supports the same sensorial work around discriminating and sequencing by length, making it a practical option for satellite classrooms, home visits, or early-cycle Primary children not yet ready for the full sequence. Teachers who work in smaller environments will appreciate having a proportionally scaled alternative that preserves the integrity of the lesson.
