Slide flags labelled −3/4, 0.6 and −1 1/2 along one number line to their exact spots — placing them IS ordering them, and the tolerance tightens every level.
Each round hands you flags labelled with negative fractions, decimals and mixed numbers; you drag every flag along a single shared number line to its spot, land a free flag strictly between two values given only as labels, or mirror a marked value to its opposite across 0. There is no readout while you drag, so the position must be reasoned from the value, and the exact spots appear only after you lock in. It drills 6.NS.7 and 7.NS.1 ordering and targets the misconception that −3/4 is bigger than −1/2 because 3 > 1. Best for Grades 7–8.
