Proportional Fraction RodsThis is a version of Arrangement 4 that lets you pick different sets of rods with a "Try Again" button. Can you arrange the rods so that every rod in a column is divided into the same number of red and blue chunks? Can you also arrange them so that each rod in a row has the same chunk size? rods that can be arranged this way are proportional. Don't forgetafter you have arranged the rods once, you can use the "Try Again" button to try to arrange a different set of rods.
