On this worksheet, students must read a line plot and answer higher level questions. Some questions are two step. For example, they must first combine two pieces of data and then subtract to find the difference. Questions also use the phrase "at least" so students will have to find "How many dogs measure at least 12 inches." So they need to be familiar with that vocabulary. There are multiple question formats: fill in the blank, multiple choice, and one where students create their own line plot. This worksheet works best with prior ruler knowledge or fraction knowledge. An answer key is also provided.
