Student Section Summary
We learned about a new kind of graph. A line plot shows data with Xs or other marks above a line with numbers. Each mark represents 1 number or 1 measurement. Line plots look like a ruler or a tape measure. We made our own line plots. Then we used them to answer questions about data.
This line plot shows data about hand spans of teachers. The line with numbers shows inches, like a ruler. Each X represents the hand span of 1 teacher.
We know that 5 teachers have a hand span of 8 inches because there are 5 Xs above the 8.
