Year 3 Maths Practice Questions Introduction for teachers and parents In this book there are single-page exercises covering most of the mathematics work that children will meet in Year 3. On each page there are some examples/hints along with a set of questions for children to answer. There is space for answers to be written in the book. Each exercise ends with a challenging question for the more able children. At the end of each page, children are invited to answer a self-assessment question. Using this book The exercises in the Maths Practice Questions books are not intended to be used in the initial teaching of new mathematics topics. However, they can be used as: • Homework activities - to consolidate work done in class. • End of topic class activities - to give children the opportunity to check their understanding of a particular topic. • Assessment tasks - allowing teachers to establish whether or not children are secure in their understanding of a topic. 3 2 4 Dactyl Publishing Tel: 01427 884450 PO Box 130 Fax: 01427 884455 1 RETFORD DN22 9YP www.dactylpublishing.com Contents Number and Place Value 3 - 10 Addition and Subtraction 11 - 17 Multiplication and Division 18 - 24 Fractions 25 - 32 Measurement 33 - 38 Geometry 39 - 41 Statistics 42 - 44 Appendix - Information for Parents 45 - 47 Notes 48 Are you ready for a challenge? 2 Number and Place Value A 1 Place value 100 10 1 5 3 8 How many hundreds are in each number? 534 has 361 has 892 has 2 538 is a three-digit number with 5 hundreds, 3 tens and 8 ones. 5 3 8 hundreds Let’s get started! hundreds hundreds What digit is in the ‘ones’ column of these numbers? 1 321 135 5 584 8 What digit is in the ‘tens’ column of these numbers? 432 3 3 What is the value of the 6 in these numbers?

I’m nearly there Appendix Information for Parents By the end of Year 3, children are expected to know the facts in this section. Parents can help by regularly asking questions to test their children’s ability to recall these facts. A little and often is the best approach and it is an activity that can always be done on journeys or during any spare five minutes. A Number bonds to 20 Children need to know all the pairs of numbers that add up to each number from 1 to 20. For example, the number bonds to 13 are: 1 + 12 = 13 5 + 8 = 13 2 + 11 = 13 6 + 7 = 13 3 + 10 = 13 4 + 9 = 13 They also need to know the related subtraction facts. 13 – 1 = 12 13 – 12 = 1 13 – 2 = 11 13 – 11 = 2 etc. It is OK to choose “number bonds to 12” and then get your child to answer 5 when you say 7. However, questions can be asked in other ways. It is important to use a range of vocabulary. E.g. What do you need to add to 5 to get 13? What is 13 take away 2? What is 7 less than 13? How many more than 4 is 13? What is the difference between 13 and 9? 45 B The 3, 4 and 8 times tables 0 1 2 3 4 5 6 7 8 9 10 11 12 x x x x x x x x x x x x x 3 3 3 3 3 3 3 3 3 3 3 3 3 = = = = = = = = = = = = = 0 3 6 9 12 15 18 21 24 27 30 33 36 0 1 2 3 4 5 6 7 8 9 10 11 12 x x x x x x x x x x x x x 4 4 4 4 4 4 4 4 4 4 4 4 4 = = = = = = = = = = = = = 0 4 8 12 16 20 24 28 32 36 40 44 48 0 1 2 3 4 5 6 7 8 9 10 11 12 x x x x x x x x x x x x x 8 8 8 8 8 8 8 8 8 8 8 8 8 = = = = = = = = = = = = = 0 8 16 24 32 40 48 56 64 72 80 88 96 3 3 3 3 3 3 3 3 3 3 3 3 3 x x x x x x x x x x x x x 0 1 2 3 4 5 6 7 8 9 10 11 12 = = = = = = = = = = = = = 0 3 6 9 12 15 18 21 24 27 30 33 36 4 4 4 4 4 4 4 4 4 4 4 4 4 x x x x x x x x x x x x x 0 1 2 3 4 5 6 7 8 9 10 11 12 = = = = = = = = = = = = = 0 4 8 12 16 20 24 28 32 36 40 44 48 8 8 8 8 8 8 8 8 8 8 8 8 8 x x x x x x x x x x x x x 0 1 2 3 4 5 6 7 8 9 10 11 12 = = = = = = = = = = = = = 0 8 16 24 32 40 48 56 64 72 80 88 96 Children should already know the 2, 5 and 10 times tables reasonably well but, if not, start with these before progressing to the 3, 4 and then 8 times tables. Division facts related to times tables Children also need to know the division facts for each times table (shown for 3 times table only). 3 6 9 12 15 18 21 24 27 30 33 36 ÷ ÷ ÷ ÷ ÷ ÷ ÷ ÷ ÷ ÷ ÷ ÷ 3 3 3 3 3 3 3 3 3 3 3 3 = = = = = = = = = = = = 1 2 3 4 5 6 7 8 9 10 11 12 3 6 9 12 15 18 21 24 27 30 33 36 ÷ ÷ ÷ ÷ ÷ ÷ ÷ ÷ ÷ ÷ ÷ ÷ 1 2 3 4 5 6 7 8 9 10 11 12 46 = = = = = = = = = = = = 3 3 3 3 3 3 3 3 3 3 3 3 Again, try to use a range of vocabulary when asking questions. E.g. What is 3 multiplied by 8? What is 8 times 3? What is 24 divided by 3? What is 1 3 of 33? C Facts about time There are: 60 seconds in a minute 60 minutes in an hour 24 hours in a day 7 days in a week 365 days in a year 366 days in a leap year Number of days in each month January 31 July 31 February 28 (29 in a leap year) August 31 March 31 September 30 April 30 October 31 May 31 November 30 June 30 December 31 Telling the time Children should be able to use all the following vocabulary when telling the time: Twelve o’clock Quarter past four Quarter to six Half past two Ten to six Five past nine They should then go on to tell the times to the nearest minute and understand the significance of am and pm. E.g. 8.04 am 5.15 pm Finally they should know how times are measured using the 24-hour clock. E.g. 8.04 am = 08:04 6.15 pm = 18:15 47 Notes 48
