Task

Provide materials to the student for Part 1.  Say:  The class voted for their favorite animal.  Point to the chart and table as you read.  John looked at the chart “Favorite Animals” and wrote the total number of animals for each category inside the table.  I think he miscounted some of the animals.  Can you fix his errors?  Point to the empty table called “Favorite Animals.”  Fill in the Favorite Animals table with the correct number of animals there are in each category.  Prompt if needed:  How many students voted for Elephants?  How many voted for Tigers?  How many voted for Monkeys? 

Part 2:

·         Compare your categories.  How many fewer students like tigers than monkeys?  Show your thinking with pictures, numbers, or words.

·         Compare your categories.  How many more students liked monkeys than elephants?  Show your thinking with pictures, numbers, or words.

Say:  Can you tell anything else about the data in the chart?
