1 Fun with Maths at Home This booklet is aimed to help you develop your child s mathematical ability and understanding at home. At the start you will find the key objectives for your child s year group. Key objectives are the main objectives children are expected to understand and apply by the end of this year. It will also include extension objectives, which they will be progressing towards. Attached to this booklet you will find resources required for some of the activities mentioned. There are addition and subtraction bonds, as well as multiplication and division tables. There will also be some useful websites with games for children to play at home. We will provide maths games for your children to play as homework every other week. These are age appropriate and will practise the skills they will be taught throughout the year. There are many ways you can help your child in maths. Adults use lots of maths at home in everyday activities, such as cooking, shopping and DIY. We use a range of maths while spending money, measuring, calculating and so on. You can talk with your child about things like: Which coins to use to pay for an ice-cream or drink How many oranges to buy and how much they weigh

2 Whether or not they are taller than their cousin / brother / sister Planning the meals for the week and making a shopping list One of the best things you can do with your child is talk to them about mathematics. Sometimes it is even more important to listen and let them explain what they are doing and why. Enjoy playing the maths games that are sent home. Please feel free to write a comment in the provided homework comment sheet in the homework folder about your child s success and enjoyment of the game. If your child is not good at working things out in their head at first, don t worry! Be positive. Praise them for what they can do and keep on working with them. What do I need to help my child with maths? Plastic measuring jugs marked with litres (l) and millilitres (ml). (Keep baby s old feeding bottles.) A tape measure marked in metres (m) and centimetres (cm). Kitchen scales that can weigh in kilograms (kg) and grams (g). Plastic measuring spoons (5ml, 10ml and so on). A watch with stopwatch or timer on it. Road maps and road atlases. Lots of games you can play together. E.g. Snakes and Ladders, Ludo, Monopoly.

3 Best of all, try to find lots of time to play and talk with your child. Useful websites: In Year Two your child will be learning to Count up to 100 objects by grouping them and counting in tens, fives or twos; explain what each digit in a two-digit number represents, including numbers where 0 is a place holder; partition two-digit numbers in different ways, including into multiples of 10 and 1 Derive and recall all addition and subtraction facts for each number to at least 10, all pairs with totals to 20 and all pairs of multiples of 10 with totals up to 100 Add or subtract mentally a one-digit number or a multiple of 10 to or from any two-digit number; use practical and informal written methods to add and subtract two-digit numbers

4 Use the symbols +, -,, and = to record and interpret number sentences involving all four operations; calculate the value of an unknown in a number sentence (e.g. 2 = 6, 30 - = 24) Visualise common 2-D shapes and 3-D solids; identify shapes from pictures of them in different positions and orientations; sort, make and describe shapes, referring to their properties Use units of time (seconds, minutes, hours, days) and know the relationships between them; read the time to the quarter hour; identify time intervals, including those that cross the hour Use lists, tables and diagrams to sort objects; explain choices using appropriate language, including 'not' The focus is working with numbers up to 100

5 Your child will be progressing towards work in Year Three Read and write numbers up to 1000 and put them in order Know what each digit is worth in numbers up to 1000 Count on or back in tens or hundreds from any number less than 1000, for example, 462, 472, 482 or 662, 562, 462 Know by heart addition and subtraction facts up to 20, for example, = 20, 12 8 = 4 Work calculations out in their head such as and Know by heart the 2, 5 and 10 times tables Do simple divisions with remainders, such as 27 5 Find simple fractions, such as 1/2, 1/3, 1/4, 1/5, or 1/10, of shapes such as a circle, square etc., and numbers Tell the time to the nearest 5 minutes Use and p, for example, know that 2.04 is 2 and 4p Solve simple number problems and explain how to work them out Recognise right angles and lines of symmetry in simple shapes

6 Guess and count Guess all kinds of things, and then count to check. Children may make wild guesses at first, but they are learning about numbers and measures in the real world and their guessing can only get better. How many steps do you think it is from here to the post office? Let s count and check. How many minutes do you think we will have to wait in the queue? Let s count and check. How many pears do you think we will get for 1? Shopping When you are shopping, your child could weigh items, add up the cost and count out the change. Car number plates One person is even and the other is odd. Add up the digits on car number plates. If the answer is even the Even person scores the point; if it s odd the Odd person scores. M376 TFN 3 and 7 and 6 makes 16. That s even, so it s my point.

7 Car number games Look at the three digits (numbers) on a car, for example 562: The biggest number you can make by rearranging them is 652 The smallest number you can make is 256 Add the numbers together ( = 13). Aim for 1 You need plenty of 10p, 5p and 1p coins and a dice. Take turns to throw the dice and take that many coins. All the coins must be of the same value (all 10ps, all 5ps or all 1ps). Add up the total value of your coins. Keep track of how much money you have collected. If the coins take you over 1, you must put your coins back instead of collecting them. The first person to get exactly 1 is the winner. How close? For 2 or 3 people You need plenty of 10p and 1p coins and a dice. Take turns to throw the dice and take that many coins. On each turn you must decide if you are going to take all 1p coins or all 10p coins. After four turns each, count up your money. Then see who has got closest to 1 without going bust. I ve got a number in my pocket! My number is less than 100 but what is it? Try to find out what it is in 20 questions. A guess is wasted so ask questions that remove groups of numbers. Is it odd or even?

8 Is it more or less than 50? Can you divide it by 5? You can use the 100 grid to help your child to become confident with doing calculations in their head. Read the numbers in order. Colour all the numbers in the 10 times table yellow (10, 20, 30, 40 and so on). Colour all the numbers in the 5 times table red (5, 10, 15, 20 and so on). Why have the tens numbers ended up orange? You can use the 100 grid to help your child to become confident with doing calculations in their head. Read the numbers in order. Colour all the numbers in the 10 times table yellow (10, 20, 30, 40 and so on). Colour all the numbers in the 5 times table red (5, 10, 15, 20 and so on). Why have the tens numbers ended up orange? Check the names of the numbers Is that number thirty-four or fourty-three? (Pointing to 34) It s Nan s 56 th birthday. Can you find her age on the grid? Count in tens, starting at any number, 14, 24, 34, 44, 54.. Use the grid whenever you are talking about numbers Look for patterns and talk about them

9 Look at the numbers in that diagonal line: 10, 19, 28, 37, 46, 55, 64, 73, 82, 91 Each number is nine more than the one before. Number squares Cover six numbers on your number square. Can you work out what they are? Phone number sums What do all the digits of your phone number add up to? For example, adds up to 31. Ask your child to find ten phone numbers in your local phone book with the same total as your own phone number. Imagine this Close your eyes and imagine that in front of you is a cube. Can you see it in your mind? What shape is one side (or face) of a cube? (It s a square) How many sides (or faces) has it got? How many corners has it got? How many edges has it got? Seeing the shape in your head is very important in maths. Try this with other solid shapes.

10 Doubling and halving Doubling and halving are very useful skills, and people who are fast at mental maths make great use of them. Your child can practice by using a bus number, a price in a shop window, or a car number plate, and doubling or halving it in their head.
