In the early stages of learning to use a Carroll diagram, the teacher should provide the students with the criteria they need to sort the shapes, objects or numbers.
As they grow confident in using their diagram, students can start to make their own criteria through which to sort things. In Key Stage 2 Year , students may use Carroll diagrams for sorting numbers and looking at patterns within numbers when learning their times tables or learning about prime numbers.

Theoretically, they can also be used throughout different subjects wherever a comparison within a set wants to be made.
Science is the most common foundation subject where they are likely to be used to support classification of animals. That being said, there is no requirement that they must be used in the national curriculum. They are tools in which classifications and grouping can take place and patterns can be seen clearly. Common areas of mathematics that lend themselves to such activities, where a Carroll diagram may be used, include the following:. We can start by looking at the first shape, which is a circle.
As one of the criteria is whether the shape is a circle or not, we can safely say that the circle will go into the top row of the template. We then need to use our knowledge of shape to know that the circle has less than four corners. It belongs in the top left section. All the other shapes are not circles, so we know that they will belong in the second row. As the first column looks at shapes with 4 corners or less, any shape that fits this criteria will go into the bottom left section.
That would be the right-angled triangle, both squares and the rectangle. The only remaining shape, the heptagon, has 7 corners and so would go into the bottom right section. The same process can be applied here.
It is a good idea to encourage children to deal with one number at a time. For example: look at the number 8 and then go through each of the criteria in turn to work out which box it should go in, then cross off number 8 from the list.
Next look at 22 and do the same, and so on. In a similar way to Venn diagrams , Carroll diagrams encourage children to sort data methodically, but also provide good revision for properties of shapes and number facts. More like this. Completing a Carroll diagram. Carroll diagram planning. Sorting with a Carroll diagram. What is a Venn diagram? In the PE example, there is an empty box. This encourages learners to think of reasons for this.
Although there are aerobic, static activities e. In the art example, learners can follow up the task by looking at paintings by different artists and then completing the Carroll diagram with the names of the paintings which have these colours. Examples of all diagrams are taken from across the curriculum. This lesson can help your students question social or governmental priorities and advocate personal viewpoint.
