General Goal(s):

Use bar graphs and tables in real-life settings.

Specific Objectives:

1. Use bar graphs and tables to solve problems.
   
2. Interpret graphs and tables.
   
3. Compare and contrast graphs and tables.
   
4. Identify the usefulness of graphs and tables in the real world.
   
5. Make predictions about the future based on trends within a graph.

Required Materials:

• Promethean Board (PB)
  
• internet connection
  
• teacher-made worksheets

Prior Knowledge:

The students should have worked with tally and number tables already.

Anticipatory Set (Lead-In):

Display a number table on the PB. Make sure it has a good many categories so that it takes children a while to take in all the information.
