Student Instructions

Write an Equation to Represent a Pattern: Cutting String

Read and follow the instructions on each page. Use the pen to record your data as you go. Use the label boxes to type your thoughts and observations. Keep your string laid out in an orderly way so that you can see what you have done. On the last page, use the photo to add a picture of what your string looks like at the end of the activity. Use the label tool to label the parts of the equation in relation to your picture. Use the mic to explain your thinking.
