Carroll Diagrams - Odd and Even

This resource is designed to develop an understanding of sorting numbers on a Carroll diagram using particular properties as criteria.

Numbers are sorted by two conditions. In Level 1 numbers are sorted into odd or even and more or less than either a number up to 10 or in Level 2 up to 99. In levels 3 and 4 sorting numbers up to 99 or 999 respectively is by odd or even and by the place value of particular digits such as 7 tens.
