Carroll Sort Numbers
Sort numbers on a Carroll diagram. Sort according to one or two properties, including: odd, even, multiples, square numbers, prime numbers, triangular numbers, numbers less than 30 or more than 50.

KS2 Primary Framework:
Year 3:
Derive and recall multiplication facts for the 2, 3, 4, 5, 6 and 10 times–tables and the corresponding division facts; recognise multiples of 2, 5 or 10 up to 1000 (Block A & B)
Use Venn diagrams or Carroll diagrams to sort data and objects using more than one criterion (Block C)
Year 4:
Derive and recall multiplication facts up to 10 × 10, the corresponding division facts and multiples of numbers to 10 up to the tenth multiple (Block A, B, D & E)
Year 5:
Recall quickly multiplication facts up to 10 × 10 and use them to multiply pairs of multiples of 10 and 100; derive quickly corresponding division facts (Block A, B, D & E)
Identify pairs of factors of two-digit whole numbers and find common multiples (e.g. for 6 and 9) (Block A & E)
Year 6:
Recognise that prime numbers have only two factors and identify prime numbers less than 100; find the prime factors of two-digit numbers (Block B)
