In these lessons, we will learn how to use Carroll Diagrams. We also have some Carroll Diagram games that involve objects and numbers.
Carroll diagrams are tables that work like Venn diagrams and are used for the purpose of crossclassification. For Carroll diagrams, two attributes are being used for sorting, with one attribute of each characteristic being the focus.
The categories of a Carroll diagram should be mutually exclusive (do not overlap), for example even
and not even numbers. In a Carroll Diagram, numbers or objects are either
categorized as having an attribute or not having an attribute.
A table is created with four cells to show the four possible combinations of these two attributes. Either the items themselves, or the count of how many items of each type, are put in the cells.
Example:
Sort the following numbers in the Carroll Diagram provided:
953, 888, 1501, 8000, 201, 2542, 450, 9349
Example:
Put the following numbers into the correct place on the Carroll diagram.
1, 2, 3, 4, 5, 6, 10, 14, 15, 20, 21, 27, 28, 35, 47, 55

Carroll Diagram Example
Using a Carroll Diagram to sort numbers based on divisibility rules.
Example:
Which of the following numbers are divisible by 4? by 9?
by 4 and 9? by neither 4 nor 9?
144, 128, 153, 235, 68, 120, 361, 424, 468
