Top Tips The secret to success is practising little and often. Use time wisely. If you would like more ideas, please speak to your child’s teacher. Talk about time - Discuss what time things happen. When does your child wake up? What time do they eat breakfast? Make sure that you have an analogue clock visible in your house or that your child wears a watch with hands. Once your child is confident telling the time, see if you can find more challenging clocks e.g. with Roman numerals or no numbers marked. Ask your child the time regularly – You could also give your child some responsibility for watching the clock : “The cakes need to come out of the oven at twenty-two minutes past four exactly.” “We need to leave the house at twenty-five to nine.” Key Vocabulary Twelve o’clock Half past two Quarter past three Quarter to nine Five past one Twenty-five to ten Children need to be able to tell the time using a clock with hands. This target can be broken down into several steps. I can tell the time to the nearest hour. I can tell the time to the nearest half hour. I can tell the time to the nearest quarter hour.

Double your threes – Multiplying a number by 6 is the same as multiplying by 3 and then doubling the answer. 7 × 3 = 21 and double 21 is 42, so 7 × 6 = 42. Buy one get three free – If your child knows one fact (e.g. 3 × 6 = 18), can they tell you the other three facts in the same fact family? Warning! – When creating fact families, children sometimes get confused by the order of the numbers in the division number sentence. It is tempting to say that the biggest number goes first, but it is more helpful to say that the answer to the multiplication goes first, as this will help your child more in later years when they study fractions, decimals and algebra. E.g. 6 × 12 = 72. The answer to the multiplication is 72, so 72 ÷ 6 = 12 and 72 ÷ 12 = 6 6 × 1 = 6 6 × 2 = 12 6 × 3 = 18 6 × 4 = 24 6 × 5 = 30 6 × 6 = 36 6 × 7 = 42 6 × 8 = 48 6 × 9 = 54 6 × 10 = 60 6 × 11 = 66 6 × 12 = 72 1 × 6 = 6 2 × 6 = 12 3 × 6 = 18 4 × 6 = 24 5 × 6 = 30 6 × 6 = 36 7 × 6 = 42 8 × 6 = 48 9 × 6 = 54 10 × 6 = 60 11 × 6 = 66 12 × 6 = 72 6 ÷ 6 = 1 12 ÷ 6 = 2 18 ÷ 6 = 3 24 ÷ 6 = 4 30 ÷ 6 = 5 36 ÷ 6 = 6 42 ÷ 6 = 7 48 ÷ 6 = 8 54 ÷ 6 = 9 60 ÷ 6 = 10 66 ÷ 6 = 11 72 ÷ 6 = 12 6 ÷ 1 = 6 12 ÷ 2 = 6 18 ÷ 3 = 6 24 ÷ 4 = 6 30 ÷ 5 = 6 36 ÷ 6 = 6 42 ÷ 7 = 6 48 ÷ 8 = 6 54 ÷ 9 = 6 60 ÷ 10 = 6 66 ÷ 11 = 6 72 ÷ 12 = 6 Key Vocabulary What is 8 multiplied by 6?
