To analyze the data that they have collected, students look for possible patterns. When looking for a linear equation, students can look for a constant rate at which the numbers increase or decrease. Once the pattern has been established, students need to look for a way to extend the pattern to other circumstances. Generally, we display patterns in math with equations. For example, if the data began at 9, and increased 5 with each additional part, we would write the linear equation, y=5x+9. Once the equation has been established, we can extend our thinking to predictions.
