  1. LINE graphs SPI 0406.5.1 & SPI 0406.5.3 SPI 0506.5.1 & SPI 0506.5.3

  2. I can depict data using tables and line graphs • I can describe the distribution of data in table or graph using median, range, and mode.

  3. What is a line graph? 1) A line graph is used to show data. 2) A line graph is used to show changes over time. 3) A line graph can show functions. http://www.mathgoodies.com/lessons/graphs/line.html

  4. Line Graph: Plant Growth

  5. RANGE Find the point that is the GREATEST Find the point that is the least…… greatest – least =range

  6. What was the range for the height of the plant? Find the point that is the GREATEST Find the point that is the least…… greatest – least = range

  7. Greatest – least = range Greatest height = 15 cm Least height = 3 cm 15– 3 =? 12 cm

  8. TEACHERS…. • PRINT THE NEXT TWO SLIDES FOR STUDENTS TO CREATE A LINE GRAPH.

  9. Let’s create a graph…..Teachers’ TV Time for a week:
