4.4+Buying+Beads+0910

 ** Big Idea ** Many important practical and mathematical applications involve comparing quantities of one kind or another; it is important to know which method to use and how we should use them. ** Essential Question ** // What methods are there for comparing things? // Spheres: c=$0.12/ 20 spheres (x) or .6x$ Cubes: c= $0.12/ 15 cubes (x) or .8x$ Cylinders: c= $0.08/ 10 cylinders (x) or .8x$ For each type of bead, you could find two unit rates. You could find the number of beads for each unit of cost, and you could find the cost for each bead. The number of beads for each unit cost would be most useful. The unit cost for each bead would be better.
