Fractions Roll
thingiverse
With Fractions Roll, students in early grades can visually understand fraction relationships and sizes through physical manipulation of 3D parts. By slipping these pieces onto a bar anchored on a sturdy base, learners practice adding and subtracting fractions. When the rolls cover the entire bar, representing a whole, they comprehend combinations and their relationships better. The instructor can customize challenges by marking up the bar.
