Mastering Divisibility Rules in Year 4–5 Maths

Pupils learn special rules about divisibility and use them to determine whether a number is divisible by 2, 3, 4, 5, 6 or 7 without dividing it out fully, and to find factors of whole numbers. They learn that all even numbers, ending in 0, 2, 4, 6 or 8, are divisible by 2, and apply similar rules further through the lesson. Questions include finding how many two-digit numbers between 1 and 100 are divisible by 2, and identifying a false statement among several given.
