6 children fit around a picnic bench. How many benches will I need for 26 children?
Cinema tickets cost £6 each. How many tickets can I buy if I have got £26?
Solving division problems
How many boxes of 6 eggs do I have if I have 36 eggs altogether?
Notation: 36 ÷ 6 =
Array:
Using known facts: I know that 6 x 6 = 36, so 36 ÷ 6 = 6
Jottings: 6 12 18 24 30 36

Ideas to help children at home
• Share out a certain number of objects between toys or family members. How many does each person get?
• Continue to practise counting in 2s, 5s, 10s and extend to 3s, 4s, etc. with KS1 children when ready
• Cut up sandwiches, cakes, pizzas, etc. into halves or quarters and ensure each part is equal
• Ask children to solve ‘real–life’ division problems and explain how they solved it
•Encourage children to use their own jottings to record their work and help demonstrate their thinking
• Support older children with the ‘÷’ notation
• Support Year 2 children with thinking about when to ‘round up’ or ‘round down’ a remainder
