Students understand the concept of a ratio and use ratio language to describe a ratio relationship between two quantities. Students use proportional relationships (e.g., speed as the ratio of distance traveled to time taken) among different types of quantities to provide information about the magnitude of properties and processes. The average walking speed of a Desert tortoise is only 0.2 mph That means these desert dwellers cannot quickly move out of the way of oncoming traffic and are. They collect data in a table, conducting multiple trials and controlling the variables, and then calculate an average and share their findings. Students determine their rate of speed while walking at a natural pace (not a race). ![]()
