Need a quick sorting activity for ratios, rates, and unit rates? You've come to the right place. This activity features 15 items to sort into three categories--ratio, rate, and unit rate. The activity takes about 10 minutes to complete if you cut the slips apart in advance, or about 15 minutes if your students do the cutting. The slips to be cut apart and glued on are included in two formats--already sorted, and mixed up.
