Line Graph Maker and Data Generator

  • Click Start. Choose a scale depending on the range of values you want to work with. Observe the values on the table. Drag the red circles (points) on the graph up to match the value and to complete the line graph. You can type in the title or the amounts ONLY when you are not in full screen mode. When the scale is large (e.g., 100, 1000) or a decimal (e.g., 0.1 and 0.01), students may have to round the values. This is a great estimation exercise!
    Line graphs are commonly used to show continuity as well as rate of growth and decline in amounts. For example, rise and fall of average temperatures from one day to the next, the number of visitors to a park from one week to the next. You can show the students linear growth or decline when the numbers increase or decrease by the same amount each time (e.g., 2, 4, 6, 8, 10, 12). Such a line graph will be a straight line.

Suggested Lessons or Activities:

  • This is really useful for teaching graphing. It is very useful when used with an interactive whiteboard for teaching and learning purposes. This program generates an infinite number of data sets using different scales for different graphs and it also gives you the option of hiding the generated data to enter your own first-hand data for when you do surveys. It also gives the students the option to print their completed graphs. Alternative, the teacher can print the blank graphs for students to complete. The table and graph will print on 2 pages. To save paper, you can print on front and back of the same sheet of paper (refer to printer dialogue).

Special Features:

  • full screen (When typing you cannot be in full screen but you can switch back and forth as you please).
  • 10 different scales to choose from (2 are decimals)
  • generate values within each scale for each line graph (unlimited possibilities)
  • hide/show values (click eye button) if you want to assign the values yourself. Type in the values.
  • use the pen to annotate (great for IWB)
  • guide lines as you drag the red point for precision
  • Print option (if you use Chrome you can save as PDF)
