LINE graphs SPI 0406.5.1 & SPI 0406.5.3 SPI 0506.5.1 & SPI 0506.5.3
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.
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/graph s/line.html
Line Graph: Plant Growth
RANGE greatest – least = range Find the point that is the GREATEST Find the point that is the least…… greatest – least = range
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
Greatest – least = range Greatest height = 15 cm Least height = 3 cm 15 – 3 = ? 12 cm
TEACHERS…. PRINT THE NEXT TWO SLIDES FOR STUDENTS TO CREATE A LINE GRAPH.
Let’s create a graph….. Teachers’ TV Time for a week: Days Sun Mon Tues Wed Thur Fri Sat Hours watched 4 3 7 2 12 5 1

STRATEGIES TO SOLVE IF MARCH HAD BEEN A CHOICE….. Step 1: Look for the months when there was an increase. Step 2: Figure how much of an increase for each of those months. Feb. to March increase = 15 lbs. May to June increase = 20 lbs.
