The old classic warhorse in a convenient travel size! Slide rules have been teaching the basics of arithmetic for ages. This one is made of robust FSC® 100%-certified wood and lets the young math whizzes practice maths, even on-the-go. Brightly colored, movable beads in five rows teach the user about numerical proportions. In this smaller format, this slide rule fits in every schoolbag!
